Seems that #YouTube has blocked a lot of the front-ends.

Both #invidious and #piped are down. (Edit: some instances may still be working)

Guys, if you care about #freedom and #privacy, it's REALLY time to start investing heavily in @peertube (in every sense of the word)

Edit: Clarify that I'm talking about YouTube front-end websites, not apps like NewPipe or yt-dlp.

(Edit2: made the language more neutral. I hope that invidious and the like bounce back from this.)
