PSA: Something has gone horribly wrong with Steam (servers now back up)

As of 6:20pm the Steam login servers seem to be back up, though slow. It is recommended that you only login directly through the client, using a website to do it puts you at risk of making a mistake and accessing a fake page, getting your details phished. Also if you think this is clickbait you are mentally deficient and don’t know what that word means.

This is all we know about the Steam problems as of 5:45pm eastern on the 25th of December. It’s noting that the response from a Volunteer Steam Community Moderator should not be considered an official statement from Valve.
