Similar story in the USAF. We transitioned the academy from Banyon Vines to TCP/IP. An entire building wing went offline every day. A team was flown out with a network analyzer. Sure enough, same time every day, the entire wing of the building went offline. Turns out, the person buffing the floor needed a place to plug in the buffer and the only place they could find had this big box with lots of blinky LED's on it, so they unplugged it, buffed the floor and plugged it back in. Half-split troubleshooting may have saved a plane flight.
- GurnB 7y agoThe best part of this anecdote is that you mentioned Banyan Vines. Spent a handful of years installing/maintaining Banyan Vines network in the early 90's.
- guytv 7y agoAmazing, and exact version of this happened to me in the Israeli Army in the 90's. Every day at around 13:30 (give and take a few minutes) the network for an entire building went offline, only to come back on line a few minutes later. ... In our version of this 'bug' - one of the NCOs unplugged the electricity to that "big box with lots of blinky LEDs" in order to plugin an electric pot, to prepare his post-meal Turkish coffee, then plug it back in once water boiled... Many resources were "thrown" at the problem, until, weeks in, someone had the splendid idea of quietly sitting around the network-cabinet around 13:30 and see what's going on.
