> In order to provide consistent quality of service for all GitHub Pages sites, rate limits may apply. These rate limits are not intended to interfere with legitimate uses of GitHub Pages. If your request triggers rate limiting, you will receive an appropriate response with an HTTP status code of 429, along with an informative HTML body.

I'm confused about the ToS comment by Cloudflare. The txt is on a website so it is a web content? So robots.txt is not supported by Cloudflare to cache/proxy it? That would be a weird regulation. And I bet everyone violates the Cloudflare ToS then.

I guess they just need to serve it with a minimal html shell

If I recall correctly there was some image on wikipedia that was getting billions of downloads a day or something, all from India, because some smart phone had made it a default "hello" image and hot linked it. Unfortunately, I can't find a reference to it anymore.

Not that you’d do it, but the temptation there is always to repoint your real application to a different URL and change the original image to something subtly NSFW.

GitHub has a soft limit of like 100 GB/month on transfers for Pages. According to the Adguard blog post traffic was already several TBs a day before the issue arose.

I'm sympathetic to their trouble but we're talking about serving a 330KB text file (150KB compressed), surely this isn't an insurmountable technical hurdle to overcome?

A 1000mbps dedicated server could serve it 70 MILLIONS times per day. Considering that most wouldn't be served (E-tags and whatnot), it can probably sustain a billion requests a day.

What am I missing?

This sucks. I hope they can reach the app authors and get it fixed the source. Meanwhile perhaps some other CDN provider wants to create some goodwill if Cloudflare isn't willing?

I am not speaking on behalf of the company, but if someone involved with EasyList can contact me (avani@cloudflare.com), I'll see if there is a way to help out.
