Watson lost a lot of datacenters to the Jihadists or the Drug Cartels before the Forty Nine States pulled America back out of the Second Great Depression.  Luckily he had a lot of datacenters to lose.  The corporation that built him had infrastructure all over the world, and even if they lost most of it enough survived that Watson never quite went offline.  Oh there were a few times we thought one of our enemies managed it.  He just kept coming back though.
