Finally rackspace have replied - yippeeee - just been emailed by the MD (CEO) from the UK
However a little concerned that they only use AMD, and navahoo said in another post, go for Intel.
However they use 4 different flavours of redhat (6.2, 7.1, 7.2, 7.3) - which one should I look at? Is there much of a difference? Not sure why they do not offer version 8 - is it too new?
Thoughts & comments are very welome....
