IE11 Display Issues

Anyone else having issues with IE11 after upgrading to 8.1?

A bunch of sites don't display properly or complain that the browser is "out of date".

On Google I'm getting an old layout (for older browsers I assume)

Facebook complains that the browser is out of date

and The Verge is completely broken (sometimes works if I refresh multiple times)

Do you think it's just a problem at my end?
