I've spent the last fortnight quietly moving things home. Not work things, my own little estate: a bookmark archive, a feed reader, a couple of cron jobs that watch prices, the bits that don't matter to anyone but me. They lived on a small VPS for years and the VPS was perfectly fine. That's rather the point. It was fine, and it was costing me real money every month to be fine, and the machine in the cupboard was sitting there at idle doing nothing.
The maths isn't really about money. A few quid a month is noise. It's that I'd stopped understanding my own setup. Everything was a managed this and a hosted that, and when something broke I was reading someone else's status page rather than my own logs. Pulling it home meant I had to actually know how it fitted together again, which is half the reason I have a homelab at all.
The trade I'm accepting is honest: my uptime is now my problem, my power bill ticks up a little, and if the broadband goes down so do my services. For a feed reader that nobody else uses, that's a fine trade. I'm not moving anything anyone depends on, and I'm not pretending the cupboard is a datacentre. It just turns out a lot of what I was paying to host elsewhere was happier at home all along.
