That's a cool project, and it's a cool trick to avoid a dependency on a large company's app. Buuut There's always going to be a dependency on your ISP, your web hosting provider's internet access and their hardware uptime/backup schedule, your neighborhood's telephone poles and wires, your utility company, your hosting company's utility company, etc. etc. etc.

We all stand on the shoulders of giants, and I try not to think about how fragile it all really is all the time.

To circumvent this, you could host something on your LAN using, for example, a Raspberry Pi. To get access from outside that network, you could use some sort of VPN/proxy/tunneling, or you could host another instance with a hosting provider and sync the two.
