Would you be willing to share a rayID you see during one of these looping challenges? I'm the PM for Cloudflare's challenge platform, and we'd love to look into this. RayIDs contain no PII so you can share publicly, or feel free to drop me an email at amartinetti at cloudflare.
We'll also release a reporting mechanism soon, so in the future you can let us know when you see these issues and we can react to them quickly.
