I am working to migrate THR from the current cluster to a new one. I would like to get this done before the weekend, but it's unclear what the timeframe will be, as testing is still ongoing. As I am writing this the new (rebuilt) host is doing a burn-in to ensure that everything will keep running under load.
When the migration happens users will see a Cloudflare message indicatating it cannot connect to the server. This is expected, and depending on how the migration goes this may last from 30 minutes to 3 hours - I won't know more until testing the various migration options is complete and I have finalized the plan.
More information is available in this thread.
As always, thanks so much for your patience.
