Final Update, Jul 11 2014 7:00 PM UTC

The service has been operating healthy since 1:40 PM UTC. We are still working on developing a permanent fix for the problem, until the fix is implemented we will be extra watchful for service health.

We are closing out this communication and will post a new blog in case the issue occurs again.

Thank you.

Update: Friday, Jul 11 2014 8:30 AM

Root cause has been identified and is related to an issue with how customer data is being queued in our processing pipeline. Our engineering team implemented a temporary mitigation to address the issue and our telemetry shows the services as healthy.  We confirmed that customer impact was limited to a delay in data processing
and no data loss occurred. 
We consider this incident as mitigated but not fully resolved and we are actively working on developing a permanent fix.  We'll provide an update by 7/11 7:00 PM UTC on the status of that fix or earlier if another impact event occurs.
