tripp:
Have never heard of anyone having died from the internet not being on, unlike power and medical equipment.
But I do agree with you that ISP's/network providers should warn about work being done and I don't mean on their website an hour before. I have had it a couple of times where i go and do a snot load of trouble shooting of my own home network only to find out after waiting on hold for 30 minutes that they do have an outage happening.
Providers often put notifications on their website but the impact is often so small they just do it without notification. I fully agree however - It is indeed something that could be improved with some providers but I assume many of the outages are caused by break and fix type jobs where they can't notify everyone. For me I can normally see an outage in the middle of the night one or two times a month but I am normally asleep at this time so "meh".
I think what the OP is saying is when your landline goes down once you've converted to Fibre. We're in a world now where most people have mobiles or somebody a few meters from them does (unless if you're out in the middle of rural nowhere where you won't have fibre anyway).
