No description of DevCrate yet.
A CDN isn't one cache. It's hundreds of independent ones, and most of them are cold. Cloudflare alone runs 300+ data centers, and each keeps its own cache. A page cached in Frankfurt is still ice cold in Tokyo, so the first visitor per region pays the full origin round trip. In our...

warmup.rocks's answer:
I run a web agency in Switzerland, and for years I believed our sites were fast because we put them behind Cloudflare and saw HIT in the headers. Then I measured from other continents: pages that loaded in milliseconds from Zurich took multiple seconds from Tokyo or São Paulo, because each edge location keeps its own cache and most of them were cold.
I built a warmer for our own client sites first, then measured 408,000 CDN requests and found a miss is 3.5× slower than a hit at the median. That data convinced me this should be a product.
warmup.rocks's answer:
The whole thing runs on a plain VPS behind Cloudflare, which keeps it fast and cheap without a pile of infrastructure.
