[ntp:questions] An archetecture question....

Okay, so here's the architecture we're looking at:

A redundant pair of stratum 2 servers (call them A and B) located in 
close phyiscal proximity to one another that will be serving time to a 
group of hosts across a high-speed WAN.  There is also an addional 
low-stratum server (call him C) located on another WAN that I could use 
as a back-up in the event of a communication loss to A and B (If I lose 
comms to one, I'll likely lose comms to both).  So what I've got is:


                                              C------------------------
                                                                                    
|
                                                                                    
|
A------\                                                                       
|
|             
\                                                                     |
|              | ------------------WAN-------------------Router/host
|              /
B-------/

Please admire my 733t ASCII skillz.

The configuration (on a Cisco Router) will look similar to:

/server A prefer
server B prefer
server C

/I know that this is a long way from an optimal configuration, but can 
you all see any glaring issues with the configuration?  Could you 
suggest a better alternative?  I've got a co-worker that is conviced 
that if C offers up a time that is radically different from A and B, 
we'll have problems.  Any thoughts?


Thanks a million,
