Using Cloudflare to keep sites fast & secure
The setup of Cloudflare is a little bit more complex than most services because you need to change your DNS. They do, however, make this process about as painless as possible. First you start out by signing up for a new account and then you put in your domain name. At this point you get a nice minute long tutorial video while Cloudflare reads your existing DNS records. For a service that does not have access to
AXFR, it is rather accurate (though I’ve noticed it will leave some records out for more complex domains). You verify that Cloudflare’s DNS has all your records (add/edit/delete as you like) and then you just need to change your Name servers to Cloudflare. After that it is just a waiting game.
As soon as your domain is up and running with Cloudflare, you’ll notice absolutely no changes… except possibly that your site loads faster. You can at any point begin to tinker with the security and CDN settings. The security comes in “Essentially Off”, “Low”, “Medium”, and “High” — each level getting progressively more paranoid. The default is medium and I’ve never had any issues with that, but if “hits = money” then you might want to turn down the security level. On the other hand some sites I run care more about the security, and we’ve turned up the security to High.
As I’ve said, I’ve had a good experience with Cloudflare. I do not currently use it on Snowulf.com, but I do run it on a number of my smaller sites and the sites of my clients. I have yet to hear of any complaints from them or their clients. A little research will find a number of people with similar good experiences, some who use it only lightly, and a few not so happy former users. Just googling “Cloudflare review” came up with mostly positive results; I had to go out of my way to find the negative (by googling “Cloudflare sucks”) — which is telling to me. No one is ever going to be 100% happy with a service, however, given that all the critical features (CDN, Security, and Optimization) are all 100% free… it’s hard to go wrong at least giving it a try.
