Question: is it even possible to have DDoS protection without using a provider of it which becomes a single point of failure? Or is it maybe possible to decouple this single feature from everything else that Cloudflare provides that could take out all the sites in the future from an unrelated misconfiguration? I don't see the centralization as a positive, but I'm wondering what percentage of the websites that were taken offline see themselves as having no choice but to use Cloudflare in order to prevent themselves from being taken down anyway from malicious actors instead of by accident.
