Bonjour Vincent,
It seems today `www.poste.ch` or `www.post.ch` (2a00:17c8:0:103::20a) is unreachable using IPv6.
Is anyone experiencing the same behaviour?
Yes, from both AS559 (Switch) and AS13030 (Init7).
It's a bit annoying because the TCP conversation starts, then stalls. Because the initial SYN succeeds, the "Happy eyeballs" mechanism fails to fall back to IPv4.
Looking at NetFlow stats, this seems to have broken around 13:12 today (12:12 UTC).
Cheers,
