Cloudflare R2 is so cheap for serving static content it's hard to believe.
But then, how are you paying other then with the money?
Well, Cloudflare tries really hard (like arbitrary restrictions hard) to make you use their DNS servers for your whole domain.
Using subdomains requires an enterprise plan.
But like, what does hosting your authoritative DNS give them?
@neo well, the opoortunity to pull off a MITM, with a certificate and all that.
Ofc this is just a hypothesis.
Maybe they disallow subdomsins only because it's a pain in the ass for the large customers, and they don't care about actually hosting the DNS.
