Well, your statement "If Tier2 goes down we have a backup (Tier 1)."  
Seems to belie that. Tier 2 is not an interlinked tier that can "go  
down", each server in tier 2 has a single link to the core, they are  
not linked to each other. An individual hub in tier 2 can go down,  
but not the whole tier.

Maybe this thread gives a clue! One person designed it expecting  
maybe a hundred users someday, the software currently in use is  
written by another with different ideas, and there are dozens of  
sysops with differing opinions.

I'd love to see more core servers added. I have one person already  
chomping at the bit. However, as Pete points out, I am not involved  
in the operational end of the APRS IS any longer, and the powers that  
be do not wish to increase the core.

The horsepower needed for a hub is actually pretty low, the tricky  
thing is getting the bandwidth.
