Did you report it?

Not yet, other than on X, because the project's comms is oriented around Discord which involves some hoop jumping.

(Update: On the way to doing that, I decided to run my tests again and they now work without Cloudflare being touchy, so I'll keep an eye on it!)

(Update 2: They just replied to me on X and said they had fixed their Cloudflare config - happy days!)
