does pingzapper work for you?

I ask because if it does, why not just accept that sometimes you have to do this. Its not reasonable to ISP's on both ends to resolve issues around internet traffic that is in between equipment they control, For every user in north america. the people that run 3rd party routing VPN's have done some of this work to optimize routing for things like video games. And they do this at a very reasonable price. I know people think they should not have to pay more to fix "broken" services. but when you want a very specific level of performance, sometimes you got to pay

I could be wrong, but I am assume that many MMO game hosting companies do work with major internet back bone providers to get routing to their data centers working better. but again, its not reasonable to expect they can address ALL issues. In this case, you just have to keep bugging them. Personally, i would just us the 3rd party routing service before waiting however.
