Man we were scrambling this morning - intermittent issues, reports of all sorts of wonkiness. Still can't verify it was related to this but it was one of the last things we looked at (because they didn't update their status page early enough)
Just ran into a bunch of my E2Es failing on innocuous POST requests. Really interested to know how Cloudflare managed to outright break POST requests going through them.
Got bit by that on my 2 businesses. Took Cloudflare a while to update their status page about it.
