Note that it is often not one ip, but a large number of ips from the same block that cause issues. AI scrapers seem to use that tactic now to get around robots.txt and limiters. See e.g. https://lwn.net/Articles/1008897/ Fighting the AI scraperbot scourge. We have currently blocked larger ranges from China and Brazil. If you are getting 304 https results on all gcc.gnu.org pages then you might have gotten caught in a ip-block-range. Please let us know your (outgoing) ip address and we'll clear it up. Cheers, Mark
