Wired has an article showing a traceroute output claiming they can see the NSA wiretap in San Francisco. I did the same traceroute to nsa.gov from New York City and have a strangely similar line in my output.

From the Wired post:

If you’re a Windows user, fire up an MS-DOS command prompt. Now type tracert followed by the domain name of the website, e-mail host, VoIP switch, or whatever destination you’re interested in. Watch as the program spits out your route, line by line.

C:\> tracert nsa.gov

In the above example, my traffic is jumping from Level 3 Communications to AT&T’s network in San Francisco, presumably over the OC-48 circuit that AT&T tapped on February 20th, 2003, according to the Klein docs.

The magic string you’re looking for is sffca.ip.att.net. If it’s present immediately above or below a non-att.net entry, then — by Klein’s allegations — your packets are being copied into room 641A, and from there, illegally, to the NSA.

Now here is MY output from NYC:

Is this actually evidence of the NSA tapping the internet?

I guess it really comes down to the fact that these are traceroutes to nsa.gov and we may just be seeing the routing to that network. I don’t see this node when I traceroute any other address.
Here is my traceroute to whitehouse.gov:


PB-G4-17:~ patrick$ sudo traceroute whitehouse.gov

19 205.160.212.222 (205.160.212.222)

I certainly don’t profess to be an internet routing guru so you’ll have to decide for yourself.
