Subject: Reachability issue from AS701


Just changed the upstream for this network and a few customers can't reach our services anymore.

According to RIPE stats, reachability, is not optimal on the north american zone, but is perfect everywhere else (see

One of the complaining customer is on AS1660 and the route breaks within AS701.

Could anyone confirm the reachability for this prefix from the US ?
Anyone at Verizon to check and fix if necessary ?

Thanks !
