From our last check on 24 Oct 2026 from London: homepage only, three fresh visits (did nothing, clicked reject, clicked accept). Server locations are approximate, from the IP addresses we connected to. Some requests after rejecting may be strictly necessary services; this is what we observed, not proof that the site broke the law. How we check · Run this site? Ask for a re-check or add a statement
