Reminds me of back when I was a kid in NYC around 2001, and first learned about traceroute and routing playing around with Linux. Late one night my Comcast Internet went down. So I called support, only to be given some message that it consumer support was closed. Did some basic ping and traceroute troubleshooting and discovered that the first hop out of Comcast to Cogent was down.<p>So being a foolish and persistent 18yo, I called directory assistance and sure enough Cogent NOC was listed. So I called them pretending to be a Comcast support employee. No questions asked. I told them the router IP that was down and they said they&#x27;d look into it. 20 min later, my connection to the outside was up. Probably fixed the Internet for several million people in NYC. The foolishness of youth has its perks.
