One of the main features of the original Arpanet project was to create a network that would be resilient to damage. At the time they were thinking in terms of nuclear war. Now it seems that Arpanet's successor gets stuffed by a bit of broken fibre. Good to see evidence of progress.
Sky 'fesses up to broken fibre cables as cause of outage woes
Sky has 'fessed up to broken fibre cables as being the cause of an outage in the north west, which has knocked a number of broadband and phone customers offline since Monday. The fault began yesterday evening, with customers taking to Twitter to complain. @SkyHelpTeam looks like a lot have lost service due to outage. Hope sky …

Re: @Kubla Cant
Every competent IP network has redundant connectivity. That's one of the fundamental definitions of IP. The only time that there isn't redundant connectivity is to individual terminating pieces of hardware hung from the network - unless the network is done on the cheap, and the redundant loops aren't closed (as appears to be the case with Sky, Virgin, Talk Talk etc....).

Sure, for less than 10000 users running at 9600Bd.
However my Internet *is* resilient to damage - if my main broadband goes titsup I can use dialup (if the POTS is still OK) or I can turn my mobile phone into a WiFi hotspot and route via the cellphone data network. I could have an arrangement with neighbours who use a different broadband provider that we can connect to each other's wifi in the event one of the providers goes down. You could even install a satellite link for backup, albeit slow and expensive.

Re: Tie t'data ter whippet and send it up street wi cobbles on
I've never understood why northern is written like :
Tie t'data ter whippet and send it up street wi cobbles on
A more accurate interpretation would be:
Tie't data te't whippet an' send it up't street wi cobbles on.
The "t" replaces 'the' and is pronounced as though it is part of the previous word, eg: I'm going to't pub, pronounced "I'm going tert pub".
( Really pedantic, but this has annoyed me since I saw a Michael Macintyre northerner sketch )

A problem
Nice spin, either it works or it does not. Where I live, if there is a "problem" it's after 24.00 on weekends, and if you try to phone them you will never get through as everybody else is phoning too, and once there was this nice lady who advised me to use the internet to get more information about their problem. I am not all that pissed off with the problem except that I am pissed off with the problem.

Verizon Wireless' got a redundant network
Verizon Wireless' got a redundant network. As they were installing 4G LTE and the required additional backhaul to each site, they also rolled out quite a bit of site-to-site microwave backhaul. In some cases, it's used to get backhaul to sites where they simply couldn't get decent backhaul to it otherwise. I remember reading a few years ago they got it set up to work as a fallback as well, with automated failover. Now when a fiber cut knocks out 1/4 of a state or whatever, the affected area can usually be fed via the microwave links from areas outside the affected area, keeping voice and (most likely slower than usual) data going.
Of course that's wireless, not DSL. Reading about Sky Broadband, it's not really clear if (to get out of the area) it'd run over some Sky-owned fiber or BT or what.

Re: Verizon Wireless' got a redundant network
Only Sky will know that. There are at least a dozen national fibre networks. Some companies own the kit in the ground, other companies lease dark fibre and put their own services on top, some are simple resellers. It's also possible to take out very long term leases on kit belonging to other people - IRUs. For only Sky to be affected suggests either Sky owned infrastructure or Sky's NTE on a service they're leasing from someone else.
