Do you mean UPC is routing Cogent through USA? Basically, UPC doesn't peer with Cogent and have it delivered by their upstreams. This is called hair pinning and it is probably one of the very few major network that has such issue with UPC.

which causes high latencies
via all other providers in CH which we have tried out, incl. and swissix, we have much better connections / less latency. also all our ISP's in germany have good connections
only UPC lames - that sucks ;-(
may someone of cablecom can check this, and contact me offlist ?
thanks in advance stephan
