Telefonica (the largest telecom operator in Spain) is having the same issue. There are a few thousands of workers that are not working; it's a disaster!
I don't mean to be dramatic here folks, but multiple coordinated infrastructure attacks are a form of warfare. This is literally shaping the battle space. Correlation is not causation and all that, but while people are standing around comparing their knowledge of how to deploy zero-day exploits and which isms it would be satisfying to blame during some future retrospective, the systems we depend on are being actively compromised.
