disagree.

i know networks who multihome to avoid this kind of problem but introduce new 
problems with greater risk because they are unable to run bgp properly (be it 
from inadequate hardware, bad config, bad administration)

my rule would be if your provider can manage an autonomous system better than 
you and multihoming isnt a requirement of your business then let them take on 
the management
