Is it just me?

Same here.

I was able to get to my team page and obviously these forums, but the league home page was missing…

The league site is working but I still can't watch the game.

Still unable to watch the game

The XFL experienced an issue that, unfortunately, caused the playback data to be lost. The games were simmed correctly and the play-by-play is correct, but the actual keyframe data for the games was lost. I apologize for the inconvenience as I know that you are in the playoffs and it's a real bummer not to get to actually watch the games... the issue has been identified, though, and should be resolved.

NFL league also hit - can't get in via old web interface, can with new.
