Well, I do have backups. This is India, so I even have a backup for the backup. I have three ISPs load-balanced, and not experienced any downtime since the beginning of the Pandemic (early 2020). I do realize them going down but we never realize until I looked them up.

It runs almost all the time, but sometimes I need to update settings, etc. which needs reboots the load balancer that distributes everything from.

:-)

And you cant do this durring a) the school day when the primary end user is not home or b) wake up at 2am and reboot it while the primary end user is asleep?

Honestly, I think your kid should break out the SLA and check what compensation they get paid for prime time outages.

Yes, lesson learnt and we have agreed to the new agreement -- no more primetime outages -- planned or otherwise.

I mean, another solution is to give warning at regular intervals beforehand (day, hour, ten minutes, 1 minute perhaps). Basically planned outages with ample warning. Of course, avoiding prime time planned outages is always good in any scenario and I'm sure goes a long way to keep all clients happy.

With that said, I doubt your 13 year old daughter client is actually paying for that level of service, so... ;-)

I believe the SLA for a 13 year old is 110% uptime, with consequences being The end of the world.

I am not a lawyer so feel free to go to court claiming that 100% uptime is the limits of mathematics or that the world will not end if <insert social media platform of choice> is not accessible for 5 minutes on a tuesday afternoon. Its a losing case every time, best just to settle up the case quietly with an extra scoop of icecream or some robux and cut your losses.
