Big changes mostly caused by Cloudflare's Universal SSL and aftermatch of POODLE.

Detailed analysys on my blog:
http://securitypitfalls.wordpress.com/2014/10/25/october-2014-results-big-changes/


SSL/TLS survey of 435987 websites from Alexa's top 1 million
Stats only from connections that did provide valid certificates
(or anonymous DH from servers that do also have valid certificate installed)
