I'm a fan of cloudflare, but I'm disappointed they didn't thank or mention nginx in this blog post. Cloudflare uses nginx, which recently released OCSP support thanks to sponsorship from Comodo, DigiCert, and GlobalSign [1].
That's very true, thanks to Maxim Dounin from Nginx[1] And Ryan Hurst[2] from GlobalSign
Making SSL faster is really important to be able to support "full https" websites, with HSTS headers[3] and Alternate-Protocol: spdy[4][5]
full disclosure, I do work for CloudFlare and on this particular feature :)

And they're launching 30 data centers (oh wait, they're deploying some machines in a DC...) and blah blah blah.
Sigh. Cloudflare is somewhat interesting, but very much still in the kiddie pool of CDNs.
