I've been inside the Facebook data building here in Iowa. Cell phone didn't work, guy I was there with explained the whole building is a Faraday cage. That it's protected well enough to survive an EMP. That was almost 10 years ago.
I'd put good money on anything newer being as well if not better protected.
The rest of the grid, sadly, is another story.
Want to see a neat party trick? Post a picture of the Facebook Data Center into Facebook. You can see it for about a day then it's gone. No one else can see it. Then you get a 3 day "warning " for some random picture you posted years before. I've done it 3 times back when I still used it.
