Ok wtf???
How does cloudflare not have DOS detection?
That was based on anecdotal evidence, at the time. The real cause was Cloudflare shooting themselves in foot again because of a bad config file.
The bad config file is somewhere in the middle of the chain of causality.
They changed database permissions, revealing a dormant bug in a database query, leading to config files being generated badly with duplicate lines, making them too large for intake by the bot detection service, which didn't have good input validation and made the process panic instead, ruining the service.
