Cloudflare
A network that sits in front of websites and serves them from locations close to the visitor.
Cloudflare runs servers in cities around the world and answers each request from whichever one is nearest, which shortens the trip a page has to make. The same network filters malicious traffic before it reaches the site itself.
It also provides DNS, static site hosting through Pages, and a way to run small pieces of server code close to the visitor through Workers.
