I know a lot of people tend to put their Dedi's in a specific location, but for the mass majority how important is this? If I ever buy a dedi I will probably just go for the DC with the best rep at time.
I don't have problem with speed, but even accessing websites over the other side of the pacific. However I wouldn't just order a server in india for example where the local packet loss is dreadful (I think its india anyway)
