In our network, we've implemented 9,000 bytes across the 
entire backbone, edge-to-edge. 9,000 bytes is safe as some 
kit can only go so high (that means effective supported MTU 
for each customer is slightly less than 9,000 bytes since we 
use some for our own MPLS and Layer 2 stuff, but that's 
still more than most customers need anyway).

Cheers,

Mark.
