Had a VP that was the head of IT at one point that used to tell a story how he took the whole company down on his first day. He was a disciplined person as well. (Was in the British Royal Navy, then later the U.S. Navy). They were in the middle of moving a lot of their services over and had a 3rd party company contracted to install some kind of new switches if I remember correctly. They set it all up, left him with the information and contact info I guess for assisting whoever was going to managing them. Well he apparently tried to log into one and managed to factory reset it somehow on accident. No idea how he did that on accident. But the company managed things from the Virgin Islands to North Carolina all the way west to Texas. It was corporate headquarters, so… No paychecks for thousands of employees across 100+ sites and the whole 9 yards. Thankfully a quick fix once so everything was back up the next day, but that’s how you make a good first impression.

Still no idea why they had a 3rd party installing those switches though… Definitely something we managed in house by the time I got there
