They caught the Chinese trying to compromise their systems, and stopped them before they got very far. In the process of investigating it was discovered that the Chinese had totally compromised a ton of other companies in the same operation. Sounds like top-tier security by Google. Nobody's perfect, and defending is so much harder than attacking that they're not even really the same industry.

They hadn't reckoned on their own government physically tapping the network cables inside of their datacenters. And it's hard to blame them. Snowden's leaks wouldn't have been so shocking if they weren't, y'know, shocking. Once they added this to their threat model, they went and encrypted all internal traffic.
