Cloud Agent Communication Error

Agents "loosing" connectivity to the Cloud Platform.  Windows agents will install client, register with platform, and appear to work for a bit.  Then they stop talking to the platform.  Agent systems are still on and running.  Service is running and can be restarted without issue.  But it never updates the agent status online.  I see the following in the agent logs:

11/12/2016 16:22:38.0661 Information: Proxy set for request.

11/12/2016 16:22:40.0611 Error: Web service returned http status: 503

It appears to talk to the platform as it seems to "transfer" data (Tx 282624/282624 completed).  then the 503 happens for no reason. This is occurring on numerous machines systematically, currently about 2k machines out of 22k.

Looking for advice and help.  Ticket is also opened.
