Hi. http://download.jitsi.org is not available either on IPv4 or in IPv6 . Check some traceroutes here debian Pastezone
I don’t think icmp is enabled to the server. But it opens without a problem in the browser. You cannot access it?
It’s fine now … It was a temporary issue from my side. I was updating a debian instance and it was not fetching updates from the repository. Then I tested the connectivity and assumed there were an issue on their side. I should have checked only the reachability over https.

Anyway, they should not block ICMP (especially ICMPv6 because it will break a lot of things) .
