Just wondering if it is normal for traffic from DE to DE to flow through NL->UK->US->FR and so increase delay nearly 100 times? Traceroute here: and there is only 4 AS, so ASPATH does not help a lot in finding such links with a horrifying optimisation. I believe there is much worse links, any software to detect this? Something like scanning one ip from larger IP blocks with icmp and comparing geotrajectoyi via geoip?

You should direct the question to whereever you are a customer.

These things usually happen when one party doesn't want to peer with another party and the one that wants to peer, will route traffic really far away to make sure that both parties are paying for the traffic, thus increasing the motivation for the other party to change their mind regarding peering.

...unfortunate series of circumstances... ;-)

but the bottom line is that the economics of it (almost always) comes on top of customer's benefit.

i have the same problem in my city, to reach some (few) networks, since some years now.

...but i guess in central europe (or in the central european internet - london/amsterdam/frankfurt/paris) you don't see that often... ;-)
