Apparently there is a server migration underway to move all the website data to a new server with shiny new hardware. This would normally be good news but I didn't receive the notification emails of the tickets they opened regarding this migration. In addition I had already ordered a new dedicated server a few weeks ago to prepare and perform a migration myself shortly.
A bit of a mess there, the website may go down and come up again with some missing posts from any that were made after they began transferring data. My apologies in advance, I'm mortified.
On the bright side, the new server will be twice as fast and should be a dream, after a few possible hiccups.
ETA: Apologies for the extended outage, in the end while waiting for them to do the transfer, today I transferred the site myself.
