My concern is...what if we lose one or two core servers for some  
reason?  Is the redundancy adequate to handle the load?

Last week, it did not appear like it was.  If one server was lost,  
when the other was already refusing connections, the remaining server  
was configured in a way which would have rejected stuff.

So, my question: How many core servers must be operational to handle  
the current number of connections (not CWOP load), today, of the APRS  
core?  Do we have that?
