When 1 server in a fleet of many goes down, multiple alerts fire

The name of this alert:
* IncreasedServerConnectionErrors
* IncreasedBackendConnectionErrors


**Problem description goes here**
* One server in a fleet of 8 barfed.  Do we care why that ONE server went down? Sure.  We totally should.  Should I get woken up at midnight cuz of one server out of 8 barfed?  No.  We have over provisioned this service, and have 7 other server that have the ability to take up the slack during the time for which this server is down.  

This server was rebooted by google.  The underlying host for which it was running had failed.

* Use this issue as a means of discussing what we can do to remove pages and woke engineers when it's not needed.  The server came back online just fine.  It's healthy, chef did it's job, haproxy knows it's back.
