Perhaps someone was rushing to release something that was going to be announced on the earnings call...
Overall I still love Cloudflare and run all my backend stuff there. It just feels simpler and cleaner than AWS but it's slowly starting to get cluttered as more features are released.
They announced that on 28/09 fyi. It's not new and they didn't change a flat fee before.
They still have the 5 € / month fee.
