Nice! Which CA are you using?

I can't reveal that at the moment. That will be part of the announcement in mid-October. I can say that this will not require anyone to install new root certs in browsers etc.

You are? ETA?

That's detailed in the blog post I was linking to above: http://blog.cloudflare.com/google-now-factoring-https-suppor...

To quote it: "Second, at CloudFlare we've cleared one of the last major technical hurdle before making SSL available for every one of our customers -- even free customers. We're on track to roll out SSL for all CloudFlare customers by mid-October."

I didn't think I could love Cloudflare any more than I already did.
