The F.B.I. seized Web servers in a raid on a data center early Tuesday, causing several Web sites, including those run by the New York publisher Curbed Network, to go offline. The raid happened at 1:15 a.m. at a hosting facility in Reston, Va., used by DigitalOne, which is based in Switzerland, the company said. The F.B.I. did not immediately respond to a request for comment on the raid.
The article mentions that it was likely that the agents did not realize the one server does not equal one website that they were taking offline. One server can contain multiple VPS or shared accounts.
