This is an old revision of the document!
Normal service has been resumed...
I had noticed that in recent days, this website had started to produce quite a few occasional '502: Bad Gateway' errors. This morning, it turned into a veritable flood, to the point where I literally could barely write anything without triggering one. I have accordingly spent a long 5+ hours trying to get things back on to an even keel, all ultimately without success. In a fit of desperation, I moved my entire website out of a Proxmox container and back onto physical hardware (albeit quite slow physical hardware!)
I trust that if you're reading this, it demonstrates that the move has achieved its goal of getting the site back online and in good order. My apologies for the outage.
