UPDATE 11:45 PM EDT: We have completed our upgrades and confirmed that everything is up and running. If you happened to see a blip in responsiveness, we do apologize; the server is up and running and better than ever now.
We are performing upgrades on our webserver hardware this evening at 11:00 PM. This may cause the control panel to be unavailable briefly. DNS resolution, mail forwarding, etc will be unaffected — only the web UI will be briefly unavailable. We’re only expecting a few seconds of downtime but will update this blog entry if that changes.
