cloudflare has a known habit of taking heavy users and forcibly converting companies from a $250/m plan to a $12,000/month plan.

some people would be happy for that to happen to bad entities like an online casino, but really, to cloudflare the business use is irrelevant and it could happen to any of us.

the lesson is to minimize your cloudflare dependencies. if you have to use it, use it in an agile method where you can move to something else quickly should you need to.
