Hugely interconnected IT systems are a little more complicated to restore from backup than a wordpress site. Especially since you need to disconnect everything, restore and ensure _nothing_ has been missed, then reconnect everything otherwise any remaining infected devices could just lead to it all happening again. This is all more complicated when those systems are driving actual real world mechanisms and business processes.

As far as I know they have backups and are working on restoring from them.

Keeping spare parts (backups) is good. But there's a difference between pulling your bicycle in the garage and replacing the inner tube and trying to rebuild your car from scratch while you're doing 60mph down the freeway.
