Landlines are from a different era of expected reliability. They carry their own power because it was considered too unreliable to depend on your home's electricity.

And that is a very healthy precaution. I really do not want to lose that security.

but it's not so necessary anymore. If my home line is down (which can happen since it's over ip), with a simple power outage, I can still call with my mobile. If my mobile is out of battery I can call with my girlfriend's mobile. Then the neighbours.

We have highly redundant communication systems compared to when landlines were the only option and SPOF in the building.

If your home line is down and nearby cell stations are not operational, then what? Pigeons? :)

It depends: what is the occasion in which the power grid goes down (or your IP carrier is down) and multiple mobile operators are down? Let's say: flooding, earthquake, riots, evil government shutting down telcos.

Then there is a high chance that also my land line would be down.

Thinking of it, I must get some homing pigeons _now_ ;)

Where do you live? I live in the Northeast US and I can remember multiple outages for my landline over the course of 20 winters and several blizzards. Roughly 5, wasn't really keeping track.

You've never had a bad connection? Or you dial a number and it doesn't go through and you have to try again? Or no trunk lines available when calling internationally?

No, I was mainly just thinking of dial tone. I have experienced "all circuits are currently busy" etc. but that's not quite the same thing in my mind as an "outage" as local calls, etc. still worked.

My landline has outages. For example, just a couple months ago, workers from the phone company intentionally disconnected my phone line while doing some tree trimming. Didn't even bother to knock on the door and let me know they were going to do it.

My landline is a digital phone form my wonderful cable company It's less reliable than the internet connection from the same company - "network is experience connection difficulties"

That is not what is generally meant by "landline".

That's what I thought when they told me it's all they offered in my area!

No phones that I could find were working on the morning of September 11th, landline or cellular.
