Dropbox drops the ball
Date: Jan. 10, 2013
Duration: Around 16 hours
Failure: The main selling point of a service like Dropbox is that you can rely on it as if it were your own local hard drive -- so when the service is unavailable for an entire day, it doesn't bode well for business.
That's precisely what happened on Jan. 10 of this year: Around 3:30 p.m. Pacific Time, Dropbox acknowledged its services were on the fritz, telling customers via Twitter that all client-syncing and file-uploading would be unavailable "for approximately the next hour."
Fast-forward to 7:09 the next morning, and -- hallelujah! -- the problem was resolved.
