We are currently seeing an outage on our IPv6 connection. This isn't a provider issue and we are currently investigating the issue with our server.
We will provide an update once we've found the issue. If you have IPv6 assigned to your hosting/reseller account please contact firstname.lastname@example.org and we will refund you for the month.
We've found the cause and a reboot to the server will be required. We will update you next with an ETA of the reboot
