Have you ever experienced a network crash? How did your team restore the network?

Example #1
"Unfortunately, in one of my previous positions, we did experience a crash of the network. This was due to a denial of service attack from an outside hacker. The first thing we did was to immediately shut down the entire network. We then discovered the port which the hacker was using to infiltrate the network and closed it. We reset the DNS server and tested it to verify that it was working properly. We then brought the network up, one segment at a time. We were satisfied that we had solved the problem and that the vulnerability had been fixed. The entire process took less than 3 hours. This was not optimal, but it was better than being down for days or having our data compromised."
