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.
Most likely it's the time for node crash detection and load balancing to take effect.
If service is that bad or intermittent, nobody would buy service there.
Yes, but what is the average company's internet downtime verses their LAN downtime for a single-campus outfit?
So instead of LAN / Exchange Server (or whatever is being used) you now have LAN / WAN / Google downtime. WAN gateway downtime is probably the weakest link in the chain, so wouldn't the total downtime be greater using something internet based?

Google is a company. Saying "Google doesn't have 100% uptime" makes as much sense as saying "Microsoft takes 40 minutes to install". What specifically are you trying to say?
That may be true, but what you were able to achieve and what you guarantee clients you will achieve are two very different things.
