On Monday, at 10.14 pm UTC, the Wikimedia server cluster experienced a total power failure, taking down Wikipedia, Wikinews, and all other Wikimedia websites.

The servers are housed in a colocation facility (colo) in Tampa, Florida, USA. They occupy two racks, with each rack receiving electricity from two independent supplies. However, both supplies have circuit-breakers in them, and both opened at the same time, leading to a total power failure. All computers immediately went down. It’s normal for fire safety regulations to prohibit uninterruptible power supplies in colos, with the colo providing its own UPS and generator instead. The circuit breakers were on the computer side of this emergency power system, so none of the computers continued to receive power to survive the breaker trip or shut down safely.

The actual reason why the circuit breakers tripped is currently unknown.

When power was restored, it was discovered that most of the MySQL databases that store the data which makes up Wikipedia et al had been corrupted. The main database and the four slaves had all damaged the data on their hard disk drives beyond the ability of the auto-correction to repair. Only one copy survived safely, on a machine that is used for report generation and maintenance tasks, which remained 31 hours backlogged while catching up after an unusually heavy update load during the previous week.

Volunteer Wikimedia engineers worked through the night rebuilding the databases from the sole good copy onto the other servers. The Wikipedia database is over 180Gb in size, making the copying process last 1.5 – 2 hours for every server it was performed upon.

Regular back-ups of the database of Wikipedia projects are maintained – the encyclopedia in its entirety was not at risk. The last database download was made on February 9; all edits since then could only have been laboriously rebuilt from logs and recovered from the damaged database requiring much more time and effort.

Limited read-only service was established late Tuesday afternoon, with editing becoming possible 24 hours after the power failure. Final repairs continue now, as well as upgrades to prevent similar issues in the future. Server-intensive features, such as categories and ‘watchlists’ that display recent changes to selected articles to registered users, remain disabled to ease the load on the recovering systems.

The process which led to the damage originated with the operating system, disk controllers, or hard drives failing to flush the data correctly.

If the power to a database server is cut mid-write, the database may be corrupted and unreadable, however the operating system, hardware, and software are designed to make this very unlikely. In a previous incident in 2004 power was also lost to a server but the database was undamaged.

To avoid such damage, each database server saves a copy of an edit to be applied to the database on a separate storage system before making the actual update to the database itself. This so-called ‘write-ahead logging’ should ensure that in the event of a system crash, the database can be rebuilt from a ‘last-good’ state by replaying the edits saved in the log.

Earlier this year popular blogging site LiveJournal suffered a similar power failure when another customer at their colocation facility pressed an Emergency Power Off button, intended for use only by firefighters. The company suffered database corruption similar to that seen at Wikimedia.

LiveJournal are now fitting UPS to their servers to ensure that they have time to shut down safely in the event of a power failure. Wikimedia was said to be investigating the possibility of fitting similar equipment at the time of this failure.

Several pundits have suggested that the use of another database, such as the proprietary database Oracle or the free PostgreSQL, would have avoided the database corruption seen at the server cluster. A post-mortem of the incident show the failure was in the operating system, or the hardware, or some combination of the two. LiveJournal, which also uses MySQL, reported similar database corruption after their power cut.

The Wikimedia foundation only allows the use of free software on its systems, and future versions of the Mediawiki software will support the PostgreSQL database.

Users are reminded that during times of system failure or excessive demand, they can still search Wikipedia using Google. The articles may be viewed using Google’s cache.

Zimbabwe has decided to abandon its currency, the Zimbabwean dollar, in favour of other currencies.

Acting Finance Minister Patrick Chinamasa announced today that Zimbabweans will be allowed to make transactions in other currencies along with the local currency. “In line with the prevailing practices by the general public, [the] government is therefore allowing the use of multiple foreign currencies for business transactions alongside the Zimbabwean dollar,” he said, adding that the Zimbabwean dollar will not be removed from circulation and would be used alongside other currencies.

This decision comes during the current period of hyperinflation, which has massively devalued the Zimbabwean dollar. Banknotes up to $100 trillion have been printed, despite the removal of ten zeroes from the currency last summer to try to make transactions easier. The official inflation rate, last updated in July 2008, was 231,000,000% a year, although independent estimates place the number as high as 6.5×10¹⁰⁸, or 6.5 quindecillion novemdecillion, percent.

Up to now, only vendors with licenses were legally able to accept foreign currencies, although the practice was widespread — private businesses altogether refuse to accept the unstable Zimbabwean dollar.

Large sections of the workforce, including teachers and doctors, have gone on strike because hyperinflation rapidly renders their wages worthless. Representative groups said salaries, now measured in trillions of dollars, are insufficient to pay for even the bus fare to work.

Zimbabwe also faces other crises, including a cholera epidemic that has claimed the lives of over 3,000 people, according to statistics from the World Health Organisation.

Buffalo, New York —Judge Justice Christopher Burns of the New York State Supreme Court has ordered a halt to an emergency demolition on a 19th century stable and livery on 428-430 Jersey Street in Buffalo, New York that partially collapsed on Wednesday June 11, initially causing at least 15 homes to be evacuated. At least two homes remain evacuated.

Burns orders that both the city and the group Save The Livery (www.savethelivery.com) have to come to an agreement on what to do with the building, and try to work out ways of saving at least some portions if it including the facade, side walls and a lift tower. Save The Livery is comprised of concerned area residents who have grown to love the building’s historic and unique character. On June 14, they won a temporary restraining order to stop demolition. The court ruled that the city was only allowed to remove material in immediate danger to residents and pedestrians, but stated that the demolition could only be performed with “hand tools.” The court also ordered that any rubble which had fallen into neighboring yards when the building collapsed, to be removed.

“It is in the interest of the city to have a safe environment–but also important to maintain a sense of historical preservation,” stated Burns in his ruling. Burns has given the sides until tomorrow (Friday June 20) to come to an agreement and has ordered both parties to return to court at 9:30 a.m. (eastern time) “sharp.” Activists of Save The Livery urge supporters of the stable to “fill the courtroom” to show “continued and ongoing support.” The hearing is scheduled to take place at 25 Delaware Avenue in the Supreme Court building, 3rd Floor, trial part 19.

Currently the building is owned by Bob Freudenheim who has several building violations against him because of the buildings poor condition. He has received at least five violations in three months and residents who live near the building state that Freudenheim should be “100% responsible” for his actions. Many are afraid that if the building is demolished, Freudenheim’s charges of neglect will be abolished.

On June 17, developer and CEO of Savarino Companies, Sam Savarino was at the site of the stable, discussing the building with residents and preservationists. In 2006, Savarino proposed and planned The Elmwood Village Hotel, a ‘botique’ hotel on the Southeast corner of Elmwood and Forest Avenues. The project was later withdrawn after residents filed a lawsuit against Savarino and the city. Wikinews extensively covered the story, and contacted Savarino for his professional opinion on the building.

“[I would] love to see it preserved. I was there to see if there was anything we could do to help, to see if anything can be salvaged. I just want to see the right thing happen, and so does the city,” stated Savarino to Wikinews who added that he was allowed inside the building for a brief period.

“The side walls are beyond repair. The roof has rotted and it could come down at any time,” added Savarino who also said that the building “below the second floor appears to be stable.” He also states that the back wall of the building, which borders several homes, appears to be intact.

“Eliminating the back wall could be a problem for the neighbors. It is not unreasonable to leave at least 12 feet” of the back wall standing, added Savarino.

Savarino did not say if he was interested in buying the property, but did state, “I am sure there are a couple of people interested” in buying the property. On Thursday, Buffalo News reported that a “businessman” might be interested in purchasing the property, though Wikinews is not able to independently confirm the report. Savarino says that with the property still slated for emergency demolition, a potential buyer could face tax fees of nearly US$300,000.

Freudenheim gave the city permission to demolish the building on Thursday June 12 during an emergency Preservation Board meeting, because he would not be “rehabilitating the building anytime soon.” Freudenheim, along with his wife Nina, were part-owners of the Hotel Lenox at 140 North Street in Buffalo and were advocates to stop the Elmwood Village Hotel. They also financially supported a lawsuit in an attempt to stop the hotel from being built. Though it is not known exactly how long Freudenheim has owned the stable, Wikinews has learned that he was the owner while fighting to stop the hotel from being built. Residents say that he has been the owner for at least 22 years.

The building was first owned by a company called White Bros. and was used as a stable for a farm which once covered the land around the building for several blocks. The Buffalo Fire Department believes the building was built around 1814, while the city property database states it was built in 1870. Servants and workers of the farm were housed inside resident quarters situated at the rear of the building on what is now Summer Street, but are now cottages where area residents currently reside. Some date as far back as 1829.

At about 1950, the stable was converted into an automobile body shop and gasoline station.A property record search showed that in 1950 at least four fuel storage tanks were installed on the property. Two are listed as 550 square feet while the other two are 2,000 square feet. All of the tanks are designated as a TK4, which New York State says is used for “below ground horizontal bulk fuel storage.” The cost of installing a tank of that nature according to the state, at that time, included the tank itself, “excavation and backfill,” but did not include “the piping, ballast, or hold-down slab orring.” It is not known if the tanks are still on the property, but residents are concerned the city was not taking the precautions to find out.

Today, the English version of Wikipedia is taking part in a 24-hour ‘blackout’ to protest two proposed U.S. anti-piracy laws, the Stop Online Piracy Act and the PROTECT IP Act. The protest mirrors similar actions from other websites including Reddit and Boing Boing. The White House stated on Saturday that they “will not support legislation that reduces freedom of expression, increases cybersecurity risk, or undermines the dynamic, innovative global internet”.

In the midst of the Wikipedia blackout, executive director of the Wikimedia Foundation Sue Gardner answered some questions posed by Wikinews’ Tom Morris about the effectiveness of, and background to, the blackout.

((Tom Morris)) Do you think the blackout is going to actually be effective?

((Sue Gardner)) Yes. In my opinion, the blackout has two main goals—to raise awareness about the dangers of SOPA and PIPA, and to encourage readers to contact their elected representatives and give their views. The first has already been accomplished: there are already more than 4,000 stories in Google News about the blackout, and it was a trending topic on Twitter almost immediately. So we know we’ve been effective in raising awareness. What remains to be seen how many people will contact their elected officials.

((TM)) What do you say to people who have decided to leave the editing community as a result of the blackout?

((Gardner)) I hope nobody stops editing Wikipedia because of the blackout. I watched the community decision-making process unfold on the English Wikipedia, and I thought it was a good one. People first started talking about SOPA more than a month ago. Jimmy started the straw poll in mid-December. Over 1,800 English Wikipedians from many different countries participated in the discussion over the last three days. As the admins who closed it noted, this is by far the largest-ever number of participants in a community discussion on English Wikipedia, and the overwhelming majority of them supported action. So I would hope that anybody who opposes the blackout would also agree that the decision-making process was a good one, and would therefore be okay to accept it, however reluctantly.

((TM)) How much technical planning went into the blackout before the community consensus was decided on Monday night?

((Gardner)) Last Thursday Geoff Brigham [Ed: Wikimedia’s legal counsel] asked engineering to do an internal assessment of the technical implementation requirements, because the community discussions at that point were suggesting there would likely be some kind of action. Engineering did an initial assessment based on e.g. the Italian blackout, implications for search engines, etc., and then a lot of work happened over the weekend. The bulk of initial development and testing happened on a sprint on Martin Luther King Day, a public holiday in the United States, and the final launch development and testing sprint happened on Tuesday.

((TM)) Does the fact that this is affecting only English Wikipedia and not the sister projects and other language projects concern the Foundation?

((Gardner)) No. My understanding is that the English Wikipedia is the only project and language-version enacting a blackout, but that several other projects and language versions are putting up supportive banners, with the Italian Wkipedians doing a clickthrough informational interstitial. The German Wikipedia decided to put up banners even before consensus was reached on the English Wikipedia, and the Arabic Wikipedia, Italian Wikipedia and Commons later made the same decision. (There may be others, that I don’t know about.) I think that’s fine: each project and each language has different circumstances that argue for different types of action, or for no action. There is no one right answer that fits everybody.

((TM)) Some have said that the lack of participation by opponents of SOPA in the commercial sector (sites of the size of Twitter, Facebook, Google etc.) is going to hamper the effectiveness of the blackout – is this a concern?

((Gardner)) No. I don’t think anybody ever expected the big commercial sites to black out: most aren’t in a position to participate in something like this even if they wanted to. For example, they might have shareholders to answer to, participation might cost them significant revenue, or it could break contractual agreements (such as a commitment to maintain a certain level of uptime, or some other service delivery). Most sites are constrained by various commercial considerations: that makes Wikipedia’s participation particularly powerful and important.

((TM)) Given both the Italian shutdown and the SOPA blackout, is the Foundation going to come up with a policy or set of conditions which limit when these kind of things happen? There are plenty in the community who support the SOPA actions but are concerned that this will set a bad precedent.

((Gardner)) Yeah, I empathize with those people and to a certain extent I share that concern. The Wikimedia movement does not have a lot of experience with advocacy, and probably mistakes will get made. At this time the Wikimedia Foundation doesn’t have any plans to develop policy governing protests or advocacy work. But, I think it probably does make sense for the Foundation to create venues for these discussions so people can share thinking and expertise. So for example, we may create a mailing list dedicated to advocacy/lobbying. And there is some good thinking starting to happen [on the project-wide protests page on Meta].

United States automobile manufacturing firm General Motors filed for bankruptcy and Chapter 11 protection from its creditors at 12:00 UTC Monday, in a Manhattan, New York federal bankruptcy court. This was the largest bankruptcy filing for a U.S. manufacturing company, and with declared assets of $82.29 billion and a debt of $172.81 billion, and the fourth largest bankruptcy filing in recent U.S. history — after the bankruptcies of {{w|Lehman Brothers|| ($691.06 billion), Washington Mutual ($327.91 billion), and WorldCom ($103.91 billion).

The filing, expected to be the first of many, was for a New York GM affiliate, Chevrolet-Saturn of Harlem Incorporated. Numbered 09-50026, it named GM as a debtor in possession, and was filed before judge Robert Gerber.

GM is to be represented throughout the filing process by Weil Gotshal & Manges, a New York law firm specializing in bankruptcy.

The chief restructuring officer, named in the filing, is to be Al Koch, a managing director at AlixPartners LLP in New York, who will report directly to Fritz Henderson, the Chief Executive Officer of General Motors.

In its bankruptcy petition, GM listed its primary creditors as:

The amount owed to UAW excludes “approximately $9.4 billion corresponding to the GM Internal VEBA”. USD22,760 millions are owed to bondholders.

Analysts have observed that the effect of the bankruptcy filing on the U.S. economy is not expected to be as major as it once would have been. One such voice, Mark Zandy, an economist at Moody’s Economy.com, commented that “Bankruptcy now is irrelevant in terms of the economic consequence of what’s happening to GM.” Such analysts believe that the economic impact of GM’s problems has already been felt, with its effects on parts suppliers and employment. They also believe that GM’s programme of accelerated payments, and its participation in a U.S. Treasury program to ensure prompt payments to parts manufacturers, will have cushioned the effect of the bankruptcy itself.

Speaking on Bloomberg Radio, David Cole, chairman of the Center for Automotive Research in Ann Arbor, stated that the fragility of the parts suppliers, the loss of whom would threaten the entire automobile manufacturing industry, was of more immediate concern than the GM bankruptcy.

Also filing for chapter 11 protection today were Saturn LLC and Saturn Distribution Corporation, subsidiary companies of General Motors.

As a consequence of the bankruptcy, General Motors Corporation (GM.N) was removed from the Dow Jones Industrial Average, and was replaced by Cisco Systems (CSCO.O), these changes scheduled by Dow Jones & Company to take effect from the opening of trading on June 8.
