I'd consider #10 a finding. If a simple port/vuln scan brings down an entire data center, you have serious problems.

I plugged an old printer into the network. For some reason the config was stuck on an old subnet that no longer existed. It created an ARP broadcast storm. We superglued the NIC shut on the printer.
