How many admins here have 30 to 60 minutes of unplanned uptime...PER MONTH!!
OMG I'd be so fired.

'For example, Gmail's availability, measured as average uptime per user
based on server-side error rates, has been north of 99.9 percent over the
last year, which works out to an aggregate of 10 to 15 minutes of downtime
per month, according to Glotzbach. That's lower, he points out, than the 30
to 60 minutes average unplanned downtime that, according to a recent
Radicati Group, hit on-premise e-mail systems, which also cost more to
acquire, install and maintain than Google Apps.'
