Failure: It all started on Monday, March 18, when many Google users faced slow load times or full-on timeouts while trying to access their Drive documents and files. That lasted for about three hours.
If only the troubles had stopped there. A day later, a second Google Drive outage kept some users from accessing the service for about two hours. Two days after that, the Schmidt really hit the fan when Drive went down for a whopping 12 hours.
Yikes. Where's Sergey's skydiving team when you need 'em?
