I believe I worked out what was going on with this. The CloudFlare protections had to be tightened up (the "prove you're not a robot" stuff) because the forum was being crippled by AI scraperbots that don't respect robots.txt. Unfortunately, while this worked to keep those bots out, an RSS reader is, in fact, a kind of bot! So people's RSS readers, including mine, were being shown the "prove you're not a robot" thing and couldn't because they are
Possibly related is that CUK moved to new ownership around that time, as you'll know if you read the newsletter. So when I wanted to let the powers-that-be know how it might be fixed (add a CloudFlare rule exempting the RSS feeds from the anti-robot protection), it turned out they were now the powers-that-weren't
Incidentally, this blocking also affected the main CUK site, which meant that the "CUK News" section in the forum sidebar has been out of date for a while, as that works by fetching the RSS feed for the main site every so often to update the headlines. Annoying, as I'd just fixed a different problem with that a few months ago
Anyway, I just noticed that the sidebar news has started updating again, suggesting the problem had been spotted and something done about it.
I went to check my RSS reader (NetNewsWire, if anybody with a Mac is looking for a good one) and it's able to subscribe to the forum and get recent posts again. So check your feeds and see if they've come back to life
