You wouldn't believe the number of public administrations with public information that have (mostly unwittingly) had some lazy contractor put Cloudflare in front of their entire site, blocking even their RSS feeds from M2M. Yes, you can send them mails and call and sometimes, if they even understand the problem, they will fix it after a few months just before the next cheapest contractor is hired and we start all over again.
Not saying Cloudflare is just an extortion racket, but it's getting closer by the day.
