+1 for cloudflare. But I don’t use their tunnel products, I just expose my ports to only their known IPs. With cloudflare you have a nice “free” waf in front with tls that points to a secure(nginx proxy) or unsecured docker container. Audiobookshelf is a great example. Is best to use their dns product too, for easy management of your public facing sites.

Companies claiming 99.9999 uptime is an absurd goal for a SLA, and wouldn’t even survive a small internet outage like a DDoS attack or Akamai outage. I remember in the 90s selling the idea of 5 9’s - 99.999% on my resume until some manager who Interviewed me asked me to state the expected downtime. I stopped claiming that number because it’s impossible without full active redundancy in different locations and not dependent on external providers like cloudflare ever going down.
And please don’t argue maintenance windows “cover it” because that’s not how they work in the real world today.
Downtime per year:
For my home lab I’m happy my stuff is online and content I hardly lose access when there’s a power outage thanks to my ups. But if I tracked I’d be closer to 95%. Good enough but I can’t wait till I just don’t care to run anything.
