At the time, RackSpace was an excellent customer service company even for smaller accounts. To this day it was the best customer service I ever worked with.
When I decommissioned the RaQ, my RackSpace rep called me and asked if they could ship the system to me. Apparently, it was the last Colbalt system they had running by years.
In hindsight it's any wonder Sun bought and trashed them. Cheap MIPS (later x86) web boxes running Linux probably absolutely ate into their margins in certain markets
