I happened to be working with Claude when this occurred. Having no idea what exactly what the cause was, I jumped over to GPT and observed the same. I did a dig challenges.cloudflare.com and by the time I'd figured out kind of what was happening, it seemed to have... resolved itself

I must say I'm astonished, as naive as it may be, to see the number of separate platforms affected by this. And it has been a bit of a learning experience too.
