I have a mp4 file (5mb) on my domain, which was attacked yesterday, the attack traffic 6t, currently my video file jumped to https://www.cloudflare-terms-of-service-abuse.com/stream.mp4, and my domain also by Cloudflare speed limit, picture I have deleted my video files and the speed limit has not disappeared.
Consider using an alternative way to deliver those files. Stream would be the best option, but I believe workers or R2 would suffice (and wouldn’t break the TOS as far as I’m aware).
Any non-HTML content is subject to 2.8. However, Cloudflare won’t terminate your project over a few images or a short video; this rule is usually enforced when you consume a lot of traffic.
