I managed to post the wanted advert with no issues at www.fleamarket.org.uk - and I can see that since I posted this morning, there are three other new adverts as well. You are right about his YouTube channel - it is still there, but without content. Looking at his QRZ page, it looks like he is giving up active ham radio activity. Like you say, I hope everything is OK there.
Odd. The URL won’t resolve for me.
Strange. I normally go there via this Sotabeams page: Fleamarket
Does that also not work?
Works for me via TOR but not anything via any other way. DNS prop seems to be reporting fine so I dunno.
Domain name set to expire in 2030 and registered by some crowd called Easily (as a Web Consultancy).
Might just be a DNS blip somewhere. Usually can take 24 hours or so to resolve if its reconciliation and prop afaik.
