pings are afflicted more by your ISP then the distance, i've seen people from the U.S getting an ping of only 60 to europe location servers, yes distance has an role but with the current connections it's safe to say that the ISP has an big part into it, he provides the cable from your house to the internet, if that cable is bad then GG you.
if you have fiber optics and live near an exchance center, you will have very low pings.. i live 50 KM of Amsterdam which has the AMX-IS center, is easy to get pings of 4/5 to UK while playing games.
you don't have to believe me about my own pings, but what i wrote here is 100% true. cables are everything now, imagine having fiber optics everywhere in the world. ping of only 110 to antartica for example..

as to stay ontopic... this is an announcement to provide info about the new IP's to ambrosia, not a support or helpdesk topic regarding pings or discussion what ping you will have from an certain country...
