Earlier this week Google posted an update about a security vulnerability with SSLv3. The new vulnerability enables attackers to decode encrypted connections. 

Google calls this the POODLE (Padding Oracle On Downgraded Legacy Encryption) attack.

The process of disabling  SSLv3 support on all of our systems began on 10/14/14.

Impact: A very small percentage of site visitors with older, out-of-date browsers may see errors when trying to make a SSL connections. The biggest impact is with Internet Explorer 6 on Windows XP or older.

SSLv3 is nearly 18 years old. All modern web browsers support newer, more secure versions of SSL.
