The network documentation pyramid: why your spreadsheets aren't enough
I've been thinking about why network documentation always feels incomplete. You know the feeling - you've got spreadsheets full of device details, beautiful network diagrams, and configuration backups. But when something breaks at 3am, you're still calling Dave from the pub because he's the only one who knows why VLAN 247 exists.
The problem isn't that we don't document things. It's that we're only capturing the bottom layer of what we actually need.
