I remember from a few years ago that one was the dedicated pipeline from
the S@H servers to the campus net and that another was the T3 line out to
cogent.

We have:

1. gigabitethernet0_1: 66.28.250.121: cogent ssl net
2. fastethernet1_0: 128.32.0.242: side A to inr-201
3. tunnel0: 169.229.0.109:
4. tunnel1:

the way I have it written down:
The Data Server is now served by a different provider: Cogent Communications,
and a 100Mbps pipe.
shserver2.ssl.berkeley.edu [66.28.250.122] 

The homepage is served by Level 3 Communications, Inc.
setiathome.ssl.berkeley.edu [128.32.18.151]

Level 3 seems to be gone from the Berkeley traceroute, replaced by
CENIC (Corporation for Education Network Initiatives in California)
which is again serviced by Cogent Comm.
