Cogent routing to AS44038 / AS3303 - swinog

11 Dec 2012

Good evening Swinog

If someone from Swisscom / Bluewin is reading here:
I know about at least three announced subnets on AS44038 / AS3303:

188.62.0.0/15
178.192.0.0/14
85.0.0.0/14

I think there is some routing issue.
All three subnets gets routed very different since 1-2 weeks from cogent zurich, see the
traceroutes made from cogent looking glass router in zurich:
