You know that customers won't behave. Prepare for it.

If a customer is infected, then the problem is on their end. The fact that
they don't have throughput is their issue, not that of the provider's. As
for collateral damage, proper monitoring of the entire network and early
warning systems allow engineers to hopefully stop the problem before it goes
critical. The spool up on this worm was massive and effected some networks
too fast to prevent them going critical. However, tracking and resolution
should easily have been within the SLA windows.

My policy: Hmm, I'm not sure. *ring* Dude, wake up. It's a critical outage.
The whole network is collapsing. Think! *rambles for 5 minutes* Oh, wait.
Never mind, I got it. Go back to sleep. Thanks.
