No one is ignoring it...

The whole freaking article is about companies paying specialists to see how secure their farms are.

My issue is that the article glides past the "physical access" part to focus on the "scary cyber weapons" part.

That's bullshit. If it was a remote exploit from an internet connected machine, sure: that's scary.

This wasn't that.

The point is that things are connected. By physically accessing one machine you bring down not just one machine but the entire network. The importance of physical security just went up by a factor of the number of machines on the network.

At some point you are going to have to focus on the network part of security. Getting physical access to one Google server shouldn't allow you to bring down all of Google.
