Cloudflare operates as a content delivery network and distributed DNS (domain name server). Its services protect website owners from peak loads, comment spam attacks and DDos (distributed denial of service) attacks.
Hello @GO54_hq, I changed my domain nameserver to a custom nameserver of @Cloudflare for speed. Since then, all the websites attached to my domain has been broken down, so I had to revert back to the default @GO54_hq nameserver and my websites are still broken. Please help.
