The thing that is bothering me about all these traces is the latency gets worse immedaitely after the tinet.net hop in New York.
If you look at the New Youk hop #7, which is tinet.net, then the next one is that 192 IP (hope #8). After that is the next hop at AT&T (hop #9), and the data has yet to leave New York, but the latency between the three hops in New York more than doubles.
This is either an extreme lad condition, which is quite possible, or something is wrong between those three hops.
Blagard, I think you are right. The normal latency should be around 120 to 150 ms, at our servers. Not sure why the tech person at tinet.net thinks 300 is normal. It should not be.
