Undocumented networks cost you time and money. When a router fails, you waste hours figuring out what it connected to. When the only person who knows the network leaves, their knowledge walks out the door.
I've seen teams spend hours troubleshooting issues that documented networks fix in minutes. The math is simple: hour documenting saves hours debugging.
Good documentation answers these questions instantly:
- What devices exist and where are they?
- How do they connect to each other?
- What IP addresses are in use?
- What's the backup config for this device?
- What changed last week that might explain this outage?
