No joke, they took away our ability to use chat support a few months ago. Why? Because we're such an important client, that they want us to have a more personal relationship, by forcing us to interact over the phone. I wish I were kidding.
This freaks me out. Live Chat is my life-blood, especially given my schedule and number of clients. Particularly regarding issues with my Sites customers.
Rackspace has folks that know how to fix a complicated issue on RHEL stack at 3am, which is nice. And, unlike a cheap host who has an SLA that guarantees 100% uptime but only refunds you for time lost, Rackspace's SLA incentivizes them to fix things ASAP. Things like a dedicated box having a hardware failure will be restored in an hour and they credit you 5% of your monthly fee for every hour over that. Or 5% for each 30 minutes of downtime due to data center issues (power, network, HVAC, etc). And they do make good on it.
