Yep, been a while since worked at a place like that, but there was definitely a crowed that would be there most days. This was mid 2000’s. Partly dried up when smoking indoors was banned, I think that was the last straw for a big part of the culture that was already drying up.

Some systems already have that. Replaced a switch yesterday and re-arranged some things on my network board and got a HomeKit notification that some things were offline and when it came back. Knowing when something goes offline isn’t as useful as keeping things up though. With something like a hardwired camera/NVR, even if your ISP service is interrupted the cameras can still record, and you can put a UPS there to keep things going, even if the rest of the network is down.
