If you look at the IP addy of the US server, it's geographic location is NYC, so just about any co-located server farm or VPS in NYC will be more than sufficient and you won't get much better especially since IB does not allow co-location at their location.
gw1.ibllc.com resolves to 207.245.107.3, which appears to be in Greenwich CT. See attached gif. Ping times from Ubiquity same as I posted previously. I have found there is a difference between server farms as far as latencies. My firm has co-lo servers in Carteret and Weehawken at 9 and 8 ms to gw1.ibllc.com respectively. Ping time from office in Greenwich 12ms even though much closer there. Ping time from office in Manhattan (lower Broadway) 8 ms. I believe Savvis maintains a direct line to IB's location from their NY hosting farm. So that might be a little faster.
Hi YeLing If you found the suitable VPS, can you share the information? I am also come from China and also looking for such a server. Thx!
Can you guys from Asia share experiences of indeed there're delays/differences between IB's HK site vs the US main site? I am from Taiwan and ping to HK is <63ms, US is > 250ms!
