This one gives me chills

[misterx]

The city of Morgan Hill, CA, lost internet, ATM network, cell service, landline telephone service, 911 service, private networks, the hospital network, fire and burglar alarms, and critical infrastructure monitoring in a matter of moments. How? Four manholes were opened, and eight fiber cables were cut.

They don't know who did it, or why.

This one gives me chills. I suspect it's a test run.
