Dropbox says that your files are safe
Dropbox announced on Sunday that they are making progress in restoring their service after going offline on Friday. As of Sunday evening, over 99% of users can access their files. However, five percent of users had trouble syncing files from the desktop client and around 20% had issues with Dropbox’s mobile applications.
“On Friday evening we began a routine server upgrade. Unfortunately, a bug installed this upgrade on several active servers, which brought down the entire service. Your files were always safe, and despite some reports, no hacking or DDOS attack was involved,” said Dropbox in a blog post. “While we restored most functionality three hours later, some users continued experiencing issues throughout the weekend across dropbox.com, our desktop client, and our mobile apps. Dropbox should now be up and running for all of you, but we’re working through a few last issues with the Dropbox photos tab.”
Dropbox keeps a history of all deleted files and earlier versions of files for around 30 days for all accounts. Dropbox uses Amazon S3 (Simple Storage Service) to hold the encrypted versions of files. Dropbox was founded in 2007 and has around 200 million users. Dropbox said that they were not hacked. The downtime was due to “routine internal maintenance.”
