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 measurement of 408,000 CDN requests, a cache miss was 3.5x slower than a hit at the median.
warmup.rocks fixes that by requesting your pages from 42 countries on 6 continents on a schedule. Each request enters the CDN network in a different region and fills the edge location it lands in: 90+ locations per warming pass.
What makes it different: verification. We record the cache status (cf-cache-status, x-cache and equivalents) of every single response and show you the hit ratio per edge location, per run. Warming without verification is hoping.
Features
Free tools, no signup: multi-location cache checker and website speed test.
Nothing to install: no plugin, no DNS change. 7-day free trial, plans from $15/month.

warmup.rocks's answer:
Most cache warmers run from one server, so they only warm the one CDN edge location that server happens to hit. CDNs like Cloudflare cache per data center, 300+ of them, and a HIT in Frankfurt says nothing about Singapore.

Developers, agencies and store owners who run sites behind a CDN (Cloudflare, Fastly, CloudFront, Akamai, bunny.net) and serve visitors in more than one region. Typical cases:
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.

Code.org uses an extremely outdated version of javascript, It's so hard to access data in array, im basically forced to do this. Cant wait to ditch this shit. Source: over 2 years ago
I'm not sure if your 4.5yo is old enough to try Scratch[1] but nothing is too young these days. My elder got into Scratch around that time. These days, my younger one is into https://code.org and she make things go around, do stuffs, etc. 1. https://scratch.mit.edu. - Source: Hacker News / almost 3 years ago
So I am using code.org to make a platforming game, and if I am halfway off of a platform I slide off of it. Idk if this is a quirk with code.org or if I did something wrong. You can check the hitboxes by pressing debug sprites in the bottom right corner. Source: almost 3 years ago
My school hosts the unit tests for digital literacy on code.org as the "assessment day" at the bottom of the unit. Is there any way to view the test before it is unlocked by the teacher on a student account? Source: almost 3 years ago
My four year old was kicked out of his preschool class, and the school recommended I set him up with applied behavioral analysis. Though it hurt to read the email from the school, I don't blame them at all, he does have impulse control issues and doesn't always pay attention when others are talking to him. He sometimes also throws things and apparently pushed another student once. Outside of the social... Source: almost 3 years ago
