Amazon’s EC2 cloud, used by thousands of major websites, crashed yesterday. The failure left users across the U.S., including Reddit and Foursquare, offline for up to 12 hours. The company said a glitch forced the system to create back-ups of everything in its storage volumes, jamming up storage capacity. Hacker group Anonymous, responsible for trying to crash the system late last year, said they are not responsible. All areas but one have been repaired.
In a similar, but unrelated incident, PlayStation users experienced outages yesterday, affecting 75 million gamers. The fix for this failure may take much longer than the Amazon snafu, with Sony representatives telling users to expect continued outages for "a full day or two." The server experienced similar malfunctions last month.
Both instances reveal the fragility of the online cloud, where reliability is king. For businesses that rely on elastic cloud computing services for revenue, Amazon’s hiccup may push customers to rethink their current external server models.
