THR will be migrating to a new server today. If all goes well this should take a couple of hours where users will just see the maintenance page.
When I make the actual switchover we should see a Cloudflare message indicatating it cannot connect to the server. While the server is down I will take the opportunity to upgrade the forum software and all addons as well, so maybe an additional half-hour for the upgrades on top of the migration.
More information is available in this thread.
As always, thanks so much for your patience.
