It comes from the Cloudflare blog.
There’s a support page about it too.
Edit: team tells me this idea never got off the ground. Did talk with some potential partners (which did NOT include Google) but didn’t happen. So if Google was throwing CAPTCHAs it wasn’t because of our IP reputation.
PS: I love all the innovation and engineering stuff you guys regularly share on the Cloudflare blog. It’s [almost] always an interesting read. Even though I’m no fan of the massive centralization your company has caused.
I don’t understand why you saw one minute block screens. That’s not right. Should be seconds.
I’m talking with the team about your other points.
This is the most serious problem with all of the major companies these days. Cloudflare, Google, Apple, etc. When you get on their "bad side", you're just screwed. You'll never even know what got them mad at you, and there's nothing you can do to recover.
The only reasonable way to deal with this is to avoid them all to the greatest extent possible. You have no control over whether or not you deal with Cloudflare, unfortunately, which makes them the worst of the lot.
That doesn't sound right. You shouldn't see a loading page for over a minute. If you're open to providing more details privately I'd love to help troubleshoot. You can drop me an email at amartinetti @ cloudflare.
Edit: see comment above.
