I had problems with YouTube sporadically returning 404 and 500 errors for valid channel feeds yesterday. Today everything has been 100%.

Peculiar behavior since yesterday...it partially loads videos, thumbnails, comment section, all the aforementioned at random times.

Using Firefox? I think Google randomly slows down and glitches Firefox on YouTube to encourage you to switch to Chrome. It seems to have gotten a lot worse for me a week ago.

No, Please check next time.
