Rackspace used to be the best in the business, they had the latest technology and top notch support. However as of late, they are falling behind on the technology and don't provide the most efficient or secure system out there. Their support is no longer what it used to be, though I will not say it's real bad, it's perhaps just average at best. Their problems started to occur when they got into acquisition mode and purchase companies that provide vertical service that they can cross sell their clients on. It appears that rather than focusing on their core products, they focused on growing these newer acquired companies. By the way, I highly recommend staying as far away as you can from their email service, unless you are fine having important emails go to their hosted spam folder. I believe their email software may be 5 to 10 years out of date as far as spam management.
