My company makes a Google Calendar synchronization app.

This morning we observed 2 Google Apps users (in two different domains) receiving stale (several days old) events from the Google Calendar API, yet their Google Calendar UI is showing the correct, up- to-date information.

I don't believe this is anything we could be doing wrong in our application, since it's only a problem for these 2 users. All of our test cases continue to work against our Google Apps test accounts and we've never seen this behavior before. Our synchronization app has been running in production since April 08.

Would someone from Google please contact me privately ASAP?
