Latency problems

do they both providers have the same number of hops between you and the target computer .....are they using fiber optic cableing all the way through the network .....the internet is not 1 service provider with 1 set of settings it is more like thousands of service providers using all diffrent hardware and software settings connected there is really no standard on how a service provider must operate there is only standard communication protocols such as TCP/IP so i'm not surprised that 2 diffrent service providers have 2 diffrent amounts of lag. go with the faster service provider.

so you want to say that there is no way I can solve problem with such a big latency (30sec+) on application that is card game which uses very small bandwidth?
Does this mean that I should switch to some other server, for instance SmartFox?

when you answer that question let me know because that means you have just hacked every internet service provider between you and lets just say for fun hong kong.
