Some time ago we found that we can't connect to ceph.com:443. Moreover we can't either ping it.

This is me. Somehow the ipv6 ip address became unassigned to the ceph.com dedicated server in DH's database. Not sure how it happened but updated the DB and forced a network update.
I am able to ping ceph.com from my home machine over HE.net tunneling:

I also verified that it is serving HTTP over ipv6:

Works for me (native v6 ip).
Thanks!
