Cloudflare operates as a content delivery network and distributed DNS (domain name server). Its services protect website owners from peak loads, comment spam attacks and DDos (distributed denial of service) attacks.
Just a quick PSA for anyone considering a paid plan with @Cloudflare - make sure you pay attention to your billing. They don't let you go without a fight... 3 months and counting.
Am I the only one that @Cloudflare keeps billing after settling my cancellation? It's been two months (billing periods in a row). Then, trying to get support is next to impossible.
