I decided to give CloudFlare a whirl as I've heard only good things about their service, it costs nothing to use the basic service, and I was curious how it would interact with my convoluted DNS setup. Page load speed seems to be the principal reason that most folks are using CloudFlare. I'm as interested in the built in threat protection as I am anything else if only because I like having as close to a zero maintenance site as humanly possible.

Now I've had time for the DNS changes to propagate out and I'm really impressed by how much faster everything seems to load. I don't have a reasonable way to test out the security features, but a quick look at the dashboard for threat protection already had a few spammers and a botnet zombie. Oooh. Exotic. After poking at it for an hour or so I'm going to keep it up and running for the time being.
