Dear Swisscom Routing-Experts
Are you not peeing at swissIX anymore?
Your webserver www.swisscom.ch (2a02:a90:c400:4001::2) gives me a hard time to be reached. Either it wants it traffic to be routed from Berne via NL, UK, US and ends in a sinkhole or it uses what looks like using private peering from tineo/netrics/finecom to the same sinkhole:

Is that a management decision or a technical issue?
