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?
The overall rate limit specified for the API has already been reached.
