The whole resize thing is fraught with problems. It was one of the main reason I moved to Rackspace Cloud, but it's just way too unreliable. I'm too scared to use it on any mission critical servers due to unpredictable downtime.
If you're under high traffic and you try to resize the server the operation time hugely blows out. There's no way to block this TCP traffic other than changing DNS settings which is obviously undesirable and you might as well just manually setup a new server if you're going to do this (which is what I now tend to do). This process should be automated. It's an obvious bottleneck and fixing would dramatically improve their offering.
I didn't really mind Rackspace having all these issues at the beginning, but after 2 years I see no progress anywhere. Unlike AWS there's very little apparent investment in the infrastructure tools. Other cloud services have matured, but Rackspace hasn't. While the support at Rackspace is awesome, there's only so often I can hear someone apologizing. I'd rather the issues just got fixed and all this friction was reduced. Incredibly disappointed.
