Yep, content delivery is intermittent. Same here. Others complaining of the same since last evening. I finally got a refresh of the current bread by restarting modem, changing VPN exit nodes, opening Catalog, clicking desired bread, then clicking Last 50 in that bread. (Just kept trying stuff until got lucky, probably everything to do with mitigation efforts on host end, and nothing to do with all the things I tried, kek).
Your mileage will vary.
I presume these symptoms indicate site is under heavy DDoS attack. Strangely, I have 3 other breads open and only the main QR General bread has these symptoms.
There's always TOR if things get really bad.
