this is the type of reason why i stopped using cloudflare. there are just too many eggs in one basket. it's as if their entire service becomes a SPOF to your infrastructure.
There will always be potential SPOF.
The core problem with CloudFlare is that they seem to have a highly-centralized take on what is normally a massively-decentralized solution-space, with large numbers of value-adds they encourage customers to use without making it clear that they treat in a haphazard manner, doing very little testing before deploying pushing-the-envelope features while simultaneously having very little in-house debugging expertise to handle serious issues.
(As a concrete example of that last complaint, Cydia was crippled for an entire day due to ModMyi turning on CloudFlare's "preloader" transformation, which apparently caused many WebKit-based browsers--including both MobileSafari and Cydia--to entirely lock up; CloudFlare seemed to go the entire day without noticing, which I continue to be utterly shocked by, and it was only after I told them how to fix it that they were able to acknowledge the issue.)
