Is 99.9% Up-Time Good Enough?

Google’s commitment to Google Apps Premier Edition availability is 99.9%. Is this enough?

Earlier this week, I posted an entry that compared 99.9% availability of a 7x24x365 system with higher availability claims for solutions that require downtime for scheduled maintenance.

Back in October 2008, Google turned to research conducted by Radicati Group, an independent industry analysis firm. The results were enlightening and resulted in Google extending the 99.9% guarantee for Gmail to all of applications within Google Apps Premier Edition.
