Companies expect their systems to be running 24/7, but cloud providers haven’t always been able to provide this level of service. Millions of customers of Salesforce.com suffered a 38-minute outage in early January 2009 and others several years earlier. The January 2009 outage locked more than 900,000 subscribers out of crucial applications and data needed to transact business with customers. More than 300,000 customers using Intuit’s online network of small business applications were unable to access these services for two days in June 2010 following a power outage.
