Dmitry,
We (as8470) are Teleglobe customer. And we experience terrible
delays on Teleglobe to UUNet interconnect points. Teleglobe's customer
support engineers insist, that the problem caused by UUNet's routes
prioritization.
But I belive that this assymetric routing initiated by Teleglobe, not
UUNet.
We are a TGO customer as well and we do not see the problem. Here's a
traceroute:

Perhaps this is fixed?
Could you please send me 'sh ip bgp 195.128.65.33' performed at
Serial3-1-1.GW1.DCA3.ALTER.NET (157.130.39.89).I am expecting to see communities or MEDs set at TG router that lowres
route priority and makes traffic to go back via _Seattle_Denver_Chicago_NY_.
Any help is _greatly_ appreciated!---------------------
