We have begun to use Cloudflare DNS caching on the website. It will allow us to block unwanted visitors and prevent more spam. It also caches quite a bit of content and saves a ton of bandwidth. 
Below is a link to their site if anyone cares to check out the features. Let us know if you have any issues.

I did come across a few Cloudflare error pages occasionally while browsing the site yesterday. Could have just been a minor hiccup as DNS changes were propagating. Haven't seen any today.
