The FBI (Federal Bureau of Investigation) was accused of bringing down a number of web sites after it raided a colocation facility in Virginia in search of servers being used to hack into CIA and other major institutions and corporations. 

The raids, which were coordinated with other law enforcement agencies and which led to the arrest of  19 year old UK national Ryan Cleary, were part of the investigation into hacking by the LulzSec Group which targeted US government departments, broadcasters and other large institutions. 

A report in the New York Times said publisher Curbed Network was reportedly forced offline while the hosting company, Switzerland based DigitalOne told its customers in an email: 'The problem is caused by the FBI, not our company. In the night FBI has taken 3 enclosures with equipment plugged into them, possibly including your server ÔÇô we cannot check it.'

The NYT reported DigitalOne's chief executive, Sergej Ostroumow as saying that the FBI was interested in the servers of one of its clients but instead took servers belonging to 'tens of clients.' It reported an email from Ostroumow, who is based in Switzerland, as saying: "After F.B.I.'s unprofessional 'work' we can not restart our own servers, that's why our Web site is offline and support doesn't work." The agents took entire server racks, perhaps because they mistakenly thought that "one enclosure is = to one server," he said in the e-mail.

Though unconfirmed, a Google cache and other hosting lists cite Coresite as the Digitalone colocation provider in Reston Virginia. Coresite operates a 285,000 sq ft facility in Reston.

DigitalOne's cache said: 'CoreSite's Northern Virginia data center is a 285,000 sq-ft facility located at 12100 Sunrise Valley Drive in Reston. The highly secure data center is designed to meet the stringent security requirements of the government and government contractors and includes 50-foot setbacks, internal and external CCTV surveillance and 24x7 on-site security staffing. In addition, the SAS 70 certified data center has biometric scanners at multiple checkpoints prior to gaining access to the data center floor.'

Coresite floated in September 2010, its IPO valued the company at $270m. Its IPO share price was $16 on a volume of 16 million shares.  Today it was trading at $16.26. 

The raid took place in the early hours of Tuesday June 21st.
