"The unexpected has happened. oohEmbed.com has become so popular that it has exhausted the free quota limit on App Engine! I'll now have to rework some of the code to implement better caching strategies and also catch over-quota exceptions and return appropriate response. Meanwhile, please try again in a few hours when the quota counter gets reset (App Engine quotas are on 24 hour basis) Also, please use the bug tracker at http://oohembed.googlecode.com/ to file bugs like this :)" - Deepak Sarda
