What is happening with the Google API service today?

Question

Hello Google API support,

Supposedly you're monitoring this forum and helping developers.

We run a sync service and use various Google APIs to sync data for our users. Today we've had a ton of errors from the Google Contacts API.

Could someone explain what is happening? It seems like problems on Google side. Will this be fixed soon?
