you do understand that for SBC (or anyone who manages customer devices) to
make a change:
1) the customer has to be notified of the change and given a reason for
2) the customer has to agree to the change (presumably they also have to
actually be contacted.... a task of it's own at times)
3) the change has to be scheduled into a maint window
4) the procedures and maintenance changes probably have to be checked over
with the 'network monkey' (as you put it) and customer
5) change happens, for 1 customer...
Wash, rinse, repeat for the other 70,000 routers you manage for
customers... This is definitely NOT a half-rack in a colo fix. Just
contacting the customers is a feat.
