What is Cloudflare?
Cloudflare is an American company, one of the world's largest providers of content delivery network (CDN) services, cybersecurity, DDoS attack protection, reverse proxy servers, and other services to improve website performance and security. This company has existed since 2009.
The main principle of Cloudflare's operation is the use of a global network of servers located in more than 330 cities around the world. For example, when a user opens a website that uses Cloudflare, their request goes through the nearest Cloudflare server. The latter caches the content and delivers it faster to the original website server.
Cloudflare's data centers are present in many countries around the world, including Ukraine.
