Dropbox apologizes for its 48 hour outage

Dropbox said Sunday it was making progress in restoring service after the popular file storage service went offline on Friday. As of Sunday afternoon Pacific time, the service said more than 99 percent of users can access their files. But 5 percent of users were having trouble syncing files from the desktop client, and about 20 percent were having issues with Dropbox’s mobile applications.

Dropbox suffered an extended outage that affected some users for over 48 hours, and — now that the service is “back up and running” for all — the company has explained exactly what happened, and confirmed that no data was affected. Initially, there was suspicion that the cloud storage service had been hacked, but they proved to be unfounded. In a post on its tech blog, Dropbox says that a bug which surfaced during a routine upgrade was responsible.
