I do not know, already tired to look for a decent VDS ...
The requirements are simple:
Russian data center, because Most of the traffic will be from Russian IP
stability to the fore
the price tag is not transcendental, but this is not the most important
sane and fast support (not like in infobox)
Now there is a server from Infobox - it's terrible. 512MB and 10% of the 3GHz Xeon under Debian5 is slower than the Majordomo shared))). Plus mega-support: I write a ticket at 9:00, in an hour I get the answer "we prepare an answer to your question, we will respond before 13:00."
