VPS were unreachable today, with they FQDN, because of GoDaddy major outage.
No a lot to do on our side, the emails were also very slow, from 2 to 4 hours late!
Some details here (GoDaddy manage 53 millions domain names).
This kind of problem was not expected, GoDaddy is one of the biggest company in this business, but we’ll find options to secure this quickly.

Update: not an attack.
Update: we are leaving GoDaddy anyway…
