Original story:
It's the day before Christmas and all through the house, nobody is using Steam, not even a mouse—because, you guessed it, Steam is down.
It's unclear what's going on, but at a little before 2 pm ET on a Wednesday, we're guessing this not routine maintenance. Steam appears to be completely gone: The unofficial Steam Status website is reporting websocket errors, and says the entire Steam store, community, and web API are offline. SteamStat page views are also jumping up, which is a pretty reliable indicator that something's gone wrong.

Downdetector is also indicating some serious issues with Steam, ongoing since a little after 1 pm ET.
P0nchik95 on the Steam subreddit has a theory—I don't know how likely it is to be accurate (not very, I suspect) but it's not terrible advice anyway:
Comment from r/Steam
GOG, naturally, did what it does, with a not-too-subtle reminder that its games work perfectly well regardless of the state of its servers.
Just imagine
