Vodafone's Spanish Network Global Failure

TKS writes "It's one of those cases you study that can send a whole network to failure but never really happens. However, this time it did. Today Vodafone's spanish nation wide network stopped working [google Translation / Original Verion] for more than 7 hours leaving eight million clients without service. Allegedly an error updating a node's software expanded to the whole network affecting mobile connections and internet access." The Fish comes in handy if you don't speak Spanish.

Sounds a lot like this old AT&T incident. Particularly the way the failure cascades between nodes.
