- The Web server can handle more traffic. With a conventional Web server, if too many people visit the Web site at the same time, the Web server can't handle the traffic, and it goes down.
- The site is protected from hacking and denial-of-service attacks. If someone tries to hack the site or knock it offline, at most they can affect one of the CDN servers. The others keep going.
- It's faster. If you are in Los Angeles and the Web server is in New York, the information has to travel many "hops" through the Internet to reach you.

There are fewer hops for the information to pass through, so it's delivered more quickly."[ref]Cloudflare: The New Face of Bulletproof Spam Hosting[/ref]

If someone has infringed your copyright, you'd certainly like to be able to find out who they are and where they are. But since online pirates would rather not have you find out this information, various companies have sprung up that make quite a nice living in hiding people. The biggest is Cloudflare.
Cloudflare's business is that of a Content Delivery Network or CDN. Normally, if you type in a web address, it goes directly to the website. With a CDN, it goes through the CDN network first. Blogger Franklin Veaux describes it thusly:
"The CDN…has a large number of servers, often spread all over the country (or the globe). These servers make a copy of the information on the Web server. When you visit a website served by a CDN, you do not connect to the Web server. You connect to one of the content delivery network servers, which sends you the copy of the information it made from the Web server.
There are several advantages to doing this:
