Reply to comment by BikerJedi in TIFU by shutting down an entire airline in 1997, costing them six figures. by BikerJedi

Well this was almost 20 years ago at this point, no idea what kind of tools they had back then. And they did get it figured out eventually. Funny stuff though.

It would have been routine. Figure out where the packets are getting lost, then go physically check the device if a remote reboot doesn't work or can't be performed. Follow standard troubleshooting. Check the cables, hard reboot it, etc. You would eventually notice it was plugged into itself if you check and trace all the cables.

Sure, it's that easy if the loop is actually at the switch or rack of switches. If it's some random place out in the building or worse a particular PC happens to have multiple network cards plugged into separate ports and someone inadvertantly enabled bridging on them, it can be a lot harder to find.
