I have a Cyclades acs-48 console server. Direct power and Ethernet drop from the ceiling with a public ip. In my subnet, but not through my routers/switches or pdus. Completely out of band, except for relying on colo power/net, which if that's not up then oob is worthless to me anyway. I have every device hooked to this. Pdus, routers, switches, vm, storage servers. That allows me to get console and power cycle every device. What more would I want? Dialup means I need to be in a place I can hook up a modem. Not too many of those. If I make a configuration mistake, need to reboot a box etc, I want to be able to access my kit from anywhere with ip connectivity. If power or network in the colo is down, then oob does me no good, and I have a dr site for that scenario. That dr site also monitors production and emails my sms address.

I certainly want to use something more modern, having run Xmodem to load images into devices or net-booted systems with very large images in the past…
I've seen all sorts of creative ways to do this (e.g.: DSL for OOB, 3G, private VPLS network via outside carrier). It is a challenge in

Isn't the biggest issue here resilience? If you have ethernet/IP as your OOB mechanism, how sure can you be that it's really "OOB"? This is, I'm assuming the fallback for when things are really, really hosed. What would happen if you needed to physically get hands into many, many pops?
