The 10 Biggest Cloud Outages Of 2011

9. VMware Cloud Foundry Collapses

VMware's Cloud Foundry development platform was racked by a pair of different blackouts in the same week, on April 25 and April 26. While still in beta at the time, the open-source Cloud Foundry service was knocked out of commission by a power outage that affected a storage cabinet power supply on April 25 around 5:45 a.m. The following day, around 10:15 a.m., an engineer that was developing an early detection plan to prevent outages like the one the previous day knocked Cloud Foundry offline with an errant keyboard tap, which took out all load balancers, routers and firewalls; caused a partial outage to portions of the internal DNS infrastructure; and resulted in a complete external loss of connectivity to Cloud Foundry.
