A few days ago; sitting outside — drinking coffee and minding my own business, I received an email from my UPS:

Utility power not available.

My homelab had lost both power sources 😮 This whole area had a power outage — a good opportunity to do a UPS and power down test 😛

One (potential) downside to running public services on your homelab, is that you expose your IP address. That may, or may not, be a problem — but here are ways around it. The simplest way is to put Cloudflare in front, but this will only handle web traffic, and is a bit of a black box.

Another, more hands-on, approach is to use a VPS (or LXC container); WireGuard and iptables. We will create a secure tunnel between the VPS/container and the homelab HAProxy instance, and forward traffic using iptables.

In our new house there is an 20 m² basement, it consists of two rooms — both 10 m². I have turned the inner room into my new home office/server room, with my electronics lab and homelab.

So we bought a new house — now to disassemble everything and prepare to move!
