Echoing some of the other comments... the place i worked at was one of the 5 biggest Rackspace customer, and that didn't stop them from regularly cutting traffic or bringing down servers for hours in some case. You might get better uptime overall from reputable providers, but ultimately it's all about distributed application/service architecture.

Absolutely. Removing SPOFs and moving to a service oriented architecture has been a major focus for us over the last few months.
