From their website: "NEWS 2023-06-16: The GMP server is under attack by several hundred IP addresses owned by Microsoft cooperation. We do not know if this is made with malice, if it is some sort of mistake, or if some of their cloud customer is running the attack. The attack targets the GMP repo, with thousands of identical requests, most of which makes our server compress the data. We're firewalling off all of Microsoft's IP addresses as an emergency response. This is a blunt response, but it is the only response which solves the problem quickly, allowing legitimate site usage to work again." "UPDATE 2023-06-18: We got a reply from somebody with an impressive title at Github. This person explains that Microsoft and Github have investigated this, and they blame a Github user and the poor GMP infrastructure. It is very interesting that they have done nothing to stop the traffic; we need to keep defending our server by firewalling off more Microsoft IP ranges as I write this 30 hours after Github's response. It is also curious that they blame the victim. (Our infrastructure is pretty resilient with powerful server-class hardware and great connectivity to the Internet.)"
