"When was the last time we updated anything?"

Everything is running smoothly. So smoothly, in fact, that you haven't touched the system in six months. The OpenWrt firmware is three versions behind. Proxmox has unpatched security vulnerabilities. Nextcloud is nagging about an unsupported PHP version.

Maintenance isn't glamorous, but it's what keeps your network alive. A regular update schedule prevents:

• Security vulnerabilities — unpatched software is the #1 attack vector
• Compatibility issues — old versions stop working with new clients
• Performance degradation — updates often include bug fixes and optimizations
• Knowledge loss — if you don't document what's running, the next person won't know how to maintain it
