Ping works for me (Init7). Seems to be resolved, though I can't check the routing via Sunrise - Cogent. Our traceroute tool is here: https://www.as13030.net/traceroute.php
I don't consider this a peering issue, as neither Sunrise nor Init7 peers with California based Amazon infrastructure. There are different transit providers in between, and as both options are showing the same result I suppose it was an Amazon problem.
But - question: Why is 20min.ch (Cloudfront client, apparently) resolving to an address which is physically in California? That seems a rather inefficient routing / CDN mapping. I suggest to change your resolver to something more decent which resolves 20min.ch to a Switzerland based Cloudfront cache. It's not uncommon that CDN mapping breaks when using 8.8.8.8 and alike instead of the providers DNS resolver.
