I've extracted just the log messages dealing with host Stratus.

Basically, you're seeing a request for data from Stratus in ALTERNATE mode, 
followed one minute later by the connection being closed by Stratus and a new 
request from Stratus for data in PRIMARY mode, followed four minutes later by 
the connection being closed by Stratus.  All this is consistent with Stratus 
automatically switching transfer modes between ALTERNATE and PRIMARY between 
Rainbow and some other upstream site.

In other words, there's no cause for concern, things are working as they should.

Do you think I should demote the log message about the closed connection from 
ERROR to NOTE?
