Asia Apac networks

More likely a couple hundred ms.  I believe what is being seen is the 
result of Cogent trying to get established in Asia.  They won't pay to 
peer with the established players, and those players don't want Cogent 
disrupting their market, so their peering in Asia is rather poor.  If 
you're successful in forcing traffic from networks on NTT or other "Asian 
service providers" to ingress on your Cogent port, you're not going to 
like the result, as that traffic will take the scenic route via the west 
coast US or possibly Europe (twice) before reaching you.

As an NTT customer, perhaps Edvinas should complain to NTT about their 
lack of peering [in Asia] with Cogent making it difficult to utilize your 
Cogent port.  Of course, that's intentional on NTT's part...so they're 
unlikely to care about your complaint.
