Honestly, the only legit reason for an outage is some natural disaster took down the entire building. I really wouldn't want my server hosted at a mice infested building anyway, or one without backup power, cheap A/C units, etc. To me, it looks much worse that your server went offline because the FBI busted into the datacenter and knocked shit around than say an earthquake took out our fiber lines.
Personally, if I heard the FBI raided a datacenter and knocked a bunch of servers offline which had nothing to do with what they were after, then I'd seriously question the security, legal team, and response team of that place. To me, it sounds like the FBI just showed up to one guy sitting in a chair watching TV and let the FBI roam free.
