New technologies = new opportunities but also new risks. If airplanes had never been invented, there would be no plane crashes.

You can postpone the roll-out of a new aircraft model for as long as you like, but at some point an accident will unfortunately occur.

Wanting progress without being prepared to bear the risks is simply not possible with VoIP and All-IP. And 0 risk is an illusion, you can only try to keep the risks as low as possible and thus the availability as high as possible.

And even with redundancy, the overall system is only as good as the weakest part. Your analog telephone will also stop working if something smokes in the control center or a truck hits the distribution box on the street corner.

Speaking of analog. This would also cause stress in the event of war, because Switzerland has not had its own telecommunications industry for a long time, i.e. the analogue equipment also comes from abroad.

By the way, I wonder why there wasn’t a single such major failure under CEO Jens Alder.

Because it was a long time ago and you don’t remember it that clearly anymore?

Swisscom malfunction

The Swisscom landline network was severely disrupted for two hours and threatened to fail completely. swisscom’s mobile telephony was also affected. It was the second such serious incident for Swisscom. The cause was a hardware error.

How badly does IP telephony actually work when we have military “trouble”. Up until now there have been ZERO problems with “analog”. In the event of war, I can’t order routers from China if there’s “stress” all around.

So I’m prepared in case of a failure:smileyvery-happy:

Fires at heights would be better!:smileyvery-happy:

But I can understand @Delta’s frustration and have to largely agree with @hed

Tschamic

@Delta

There are also good solutions for SMEs today that are suitable for IP telephony; they are third-party providers and are also available in Switzerland.

Customer center failure

Since last Saturday the Kundencenter has only been working partially and the malfunction has still not been resolved…

Here in the 5400 area, the Kundencenter works without any problems, otherwise call the hotline 0800 800 800

N.B. There is also no general error message!

I still think it’s cool if the outsourced call centers take off like this, as soon as you say hello (you’re still hoping for Swiss German…)

“Can’t help them”

Then the attempt was made to forward it to the tech department, but this was left alone because it would already be an admin question…

I can call tomorrow and maybe it will work then.

mkay, very special 😄

The problem is that all the big telcos in Europe buy from the same supplier, so redundancy doesn’t help. See 04.12.15 Deutsche Telekom. There are rosy times ahead of us.

P.S. Swisscom has to be liable for the failure and millions are wasted again.

72. million for violating the Comco and other cases are still in the pipeline.

Where is this supposed to lead???

Ultimately, customers are finally paying for Swisscom’s bullshit.

@Delta unfortunately the world is becoming smarter and therefore more complex. Your claim “If I have 5 headquarters in the country, 4 won’t fail” is not true. If certain unknown worst-case errors occur, an entire infrastructure can be affected. See article D-Telekom Radius server, no access.

Clear, open, honest communication:

[http://www.20min.ch/finance/news/story/-Koennen-nicht-vermeiden--dass-ein-Netz-ausstieg--16558401](http://www.20min.ch/finance/news /story/-Can’t-avoid-a-network-dropping–16558401)

The Kundencenter in Interlaken is still disrupted. I had already called the hotline on Saturday and the Swiss-wide fault was activated there.

To be honest, the Radius server was definitely designed to be redundant. Even with redundancy there is no such thing as 100% security, that should be obvious to everyone. Of course the customers are annoyed, even if I had been affected myself.

Speculation: maybe it was a hacker attack in favor of the public service initiative. Such failures from Swisscom bring quota.
