On September 28th, Youtube started erroring saying that PBL is over it's quota. Without warning the quota was set to 0, so PBL is always over quota now. I don't know why Youtube did this all of a sudden without warning.
In the past, I have requested higher quota limits, but have been denied with the following answer
Policy I.1 (Additional Prohibitions)
I will try to bring back PBL, but unfortunately it's very hard for a small developer with a hobby site to get any response from Google. Sorry to everyone that has come to PBL and expected continual service.
Anyway we've had a good run and thanks for everyone who has reached out to me. I wish I could promise this site will be fixed, but given this site relied upon youtube and they have blocked PBL, it's not looking great.
