Google Apps Gets a 99.9% Guarantee

David Gerard passes along a posting on Google's official blog announcing that they have extended the three-nines SLA for the Premier Edition of Google Apps from Gmail alone to also cover the Calendar, Docs, Sites, and Google Talk services. 99.9% uptime translates to 45 minutes a month of downtime, and the blog post puts this in context with Gmail's historical reliability, which has been between three and four times as good over the last year (10-15 min./mo.). It also claims, based on research by an outside group, that Gmail's historical reliability beats that of in-house hosted solutions such as Groupwise and Exchange, on average. Reader Ian Lamont adds an article in The Standard that digs down into the details of the SLA, revealing for instance that outages of less than 10 minutes aren't counted against the monthly 45 minutes.
