While Dropbox can be a highly useful tool for accessing documents from any device, up time is the key aspect to delivering on that value proposition. On Jan. 10, Dropbox became the first major company in 2013 to suffer a substantial loss of service. The service interruption, which lasted in excess of 15 hours, was caused by a synchronization issue between the client software and the servers. During the outage, the company's estimates for restoration were substantially understated, which tended to increase the angst expressed on the Internet by frustrated users who were unable to access their documents.
To keep its users up to date on the situation, Dropbox turned to Twitter, regularly sending tweets. "Creating/joining shared folders, and creating shareable links to files, also affected. We appreciate your patience as we resolve this issue," said Dropbox's operations team in a Jan 10 tweet.
