Apologies to folks on #MastodonAppUK and #Universeodon - We identified an issue whereby we had failed to spot that threads.net was added to the block list we were using.
This is my bad and I missed on both servers the fact it had been added to the block list when I reviewed the domains to bring in, I'm not quite sure how I missed it but can only apologise.
If you were following one of the folks on Threads (Not that there are many yet) you will need to re-follow unfortunately.
