Is this service affecting? Doesn't look like an incorrect route this seems to be an anycasted network.

Shoving 4 million subscribers manually through the same route is a waste of capacity.

You call it 'optimal routing' - see my document above for why, according to the routing protocol, the US route is optimal.
I respect the need to balance across multiple links but of course one would expect an isp to have enough excess capacity cover a route going down in an outage so the fact VM are routing people over america doesnt sit well with me I'm afraid. Using multiple routes is fine, routing people over america to holland is not. I have only had this kind of routing on an isp before once, guess who the isp was?

nildram, entanet, aaisp, xilo, easynet, freeserve all manage to avoid it.
