Root Cause Analysis:

Level 1 engineer caused voice mail outage for half of the network.
Forwarded all voice mail calls to one number.
This effectively DOS’d the one number and resulted in a large prime-time outage
When questioned, the Engineer claimed “I was just seeing what that box did. I wasn’t sure so I just put a phone number in.”
