问题:

Over the past 24 hours we had a large number of TubePress users report an error message from YouTube:

Serving Limit Exceeded

Most of our users have their own Google API Key, and our cloud-hosted TubePress installation isn't anywhere close to hitting the daily quota. I can't find any documentation on this particular error message, nor can I understand why it would suddenly present itself on so many sites with different keys.

Could anyone explain what's going on?

回答1:

Even the reason of failure is about quota, it has nothing to do with the quota because the default limit is largely enough. The problem is the new Youtube anti-spam algorithm deployed at the end of last month. Unfortunately it impacts negatively on the normal users.

回答2:

This is probably because your "Per-user limit" is set too low. You can up it by going to Google Developer console -> APIs -> Enabled APIs -> <the API that's causing you trouble> -> Quotas and set "Per user limit" higher.
