I don't know the details of the email SLA, but for infrastructure: power, networking etc. on our hosted Rackspace servers, we have a 100% SLA. And it's not a lame prorated thing: they pay 5% of the monthly cost back for 30 hours of downtime. So 99% power/network uptime in a month would cost them 70% of what we pay per month. http://www.rackspace.com/managed_hosting/support/servicelevels/managedsla/ http://www.rackspace.com/managed_hosting/support/serviceleve...
