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:
