Apologies if somebody else should be handling this, but I think it's yours? :)

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!
