When the blocks happen, does it take GitHub with it for you? I'm on Vodafone (in Spain) and it's just a few Cloudflare IPs that get blocked during the matches, never had GitHub unavailable, as Microsoft doesn't use Cloudflare for GitHub, AFAIK.
Cloudflare seems to be the most common victim, but I've seen Fastly get banned out as well (which seems to be what GitHub uses as their CDN in the EU)
