Looking at the Wikipedia page, the two EOL'd environments that stand out are:
- Android browser on Gingerbread (and older) - hopefully this'll be solved soon, Gingerbread is finally disappearing but it's taken a while.
- Internet Explorer on Windows XP.
Everything else seems to be the kind of environment where if you're still using a browser that cannot support SNI then you're probably running into all kinds of problems anyway.
(I would like to think that Windows XP users are using Firefox these days, but...)
Question: aren't there privacy issues associated with SNI? http://tools.ietf.org/html/rfc... shows no attempt to munge the server name. So even though a third party might not be able to determine what content you're trying to access, they probably can intercept - albeit with the victim experiencing an interuption in service - the hostname and determine whose content you're trying to view.
