Where I work, the DevOps people took over some of the "Ops" bits and since the beginning of the month guest wi-fi has stopped working at one of my sites. I have narrowed it down to the fact that clients attempting to join that specific SSID are no longer being given an IP address.
When I explained it to the lady in charge, she looked at me blankly. I know she desperately wanted to ask what a DHCP server was, but she's aware of her reputation, and she knows I'm a gossip so she didn't.
It's still not fixed. I'm pretty sure it's because the "Director of Excellence" hasn't had a chance to Google "DHCP Server" yet. She'll get around to it sometime I suppose.
Her boss lives half way around the planet and probably doesn't understand any of it either, so there's no point talking to him.
