A few weeks ago, I posted a review on Cloudflare. Since then, they've outdone themselves yet again, by offering IPV6 resolution for all cloudflare-enabled sites.
As I use Linode, I technically already had IPV6 available for my site. However, due to the fact that Cloudflare uses a DNS based system to provide their (excellent) service, I wasn't able to take advantage of it. Now, with a simple click of a button in my Domain Settings, IPV6 is once again available for my site.
Way to go, Cloudflare!
