> Sounds like their EPC/packet core was compromised pretty seriously.

Given the issues affected fixed voice, TV, and value added services like voicemail, I wonder if it was upstream of the EPC in the OSS/BSS environment like the customer database?

An issue in the EPC wouldn't usually take out fixed line voice and digital TV services. Maybe a single point of failure in their enabling IT?

Oh, I missed the TV etc. impact - risk of idle speculation, I suppose. Yeah, OSS/BSS or enabling IT seems more likely, though I'm struggling to understand how a fallback to 3G would fix that. Supposedly customer information wasn't compromised.

One can hope that Vodafone will provide a decent external postmortem given the impact to Portuguese emergency services etc.
