It's interesting that Cloudflare is doing public shaming here. That's a good thing in this case, isn't it?
It looks like the "other cloud providers" corrected their problems, or something. Since Cloudflare was able to generate a usable signature, they could have used it in their routers to blackhole the traffic. Guessing here... It's been years (late 90's/early 2000's) since I've had to deal with enterprise networking.
