We still host some dedicated servers at Rackspace and while the technical side has continued to be solid their phone support is awful now. I used to call in and have a specialist on the phone very quickly, now I get handed off to an obviously off-shore support person who I think is running a script before being escalated to a proper specialist... when available. We've been with them for almost 20 years but I think in the next couple that's going to change.
