Hey there, Accessing https://gcc.gnu.org from some of our machines on the Cloudflare network returns HTTP 403 responses for any path at that url, e.g. https://gcc.gnu.org/pub/gcc/releases/gcc-14.1.0/gcc-14.1.0.tar.xz. This only happens for some of our colos, which suggests there's some kind of IP range filtering going on. Does anyone know who to contact about this to figure out what's happening? Things work OK if making the request using IPv6. $ curl -4 -L https://gcc.gnu.org/pub/gcc/releases/gcc-14.1.0/gcc-14.1.0.tar.xz <!DOCTYPE HTML PUBLIC "-//IETF//DTD HTML 2.0//EN"> <html><head> <title>403 Forbidden</title> </head><body> <h1>Forbidden</h1> <p>You don't have permission to access this resource.</p> </body></html> Thanks, Matt
