I would imagine the tech used in the device you linked to has been in use for quite some time. Nothing stated in the Rackspace or other ISPs posts says anything about the routers in place at these facilities. They're all quite careful to say how secure the customer's "stored data" is safe on the "servers" - nothing is said about data flows through routers.
I note there's been no statements - suspiciously scripted or not - from the likes of Juniper, EMC, HP, Dell, Cisco...
The social media company presumably-NSA-supplied denial script says "no direct access to servers".[1] I wonder just how few bits of networking gear (or switch OSs) you'd need to root - gear that sits between the SSL termination and the servers - to not even need to ask for "direct access"?
[1] In fairness - perhaps that turn-of-phrase only appeared in every CEO denial because it was a direct quite from the WaPo article.
