Level 3 - "legacy" Wiltel/Looking Glass bandwidth

Thu Jul 2 16:38:23 UTC 2009

We have an old Wiltel DS3 homed from their Anaheim POP... all traffic that's 
not going to destinations on the old 7911 backbone seems to be backhauled to 
Level3 in San Jose before getting anywhere else, like so:

 1  (internal)
 2  (internal)
 3  (internal)
 4  anhmca1wcx1-atm10-0-0.wcg.net (64.200.142.169)  8.017 ms  8.596 ms  8.138 ms
 5  anhmca1wcx3-oc48.wcg.net (64.200.143.65)  9.325 ms  8.056 ms  9.485 ms
 6  64.200.249.122 (64.200.249.122)  79.108 ms  251.438 ms  222.596 ms
 7  64.200.249.142 (64.200.249.142)  16.357 ms  16.167 ms  17.004 ms
 8  te-3-2-70.car4.SanJose1.Level3.net (4.68.110.25)  12.568 ms  13.195 ms  13.384 ms

So they don't seem to interconnect 7911 and 3356 in Los Angeles. We complained 
about this a year ago and they basically said, "tough, you bought IP transit, 
we're giving you IP transit".

Anyway, so in the meantime we bougt a new gig-e to 3356 in San Jose...

 1  (internal)
 2  (internal)
 3  (internal)
 4  (internal)
 5  ge-x-x.car4.SanJose1.Level3.net (4.71.x.x)  9.063 ms  7.780 ms  8.460 ms

So it almost looks like my gig-e in San Jose is off the same router they 
backhaul 7911/Anaheim via.

I wouldn't take a new connection to 7911 unless you're okay with this sort of 
thing. Performance has been fine other than the 5-10ms of extra latency, but the 
asthetics bug me more than anything. If they communicated more about what 
they're doing on the 7911 net and what the PLAN is for transitioning things, I'd 
be happier. But it's been this way for years now so we're just disconencting the 
old one, which is probably what they're waiting for everyone to do rather than 
really merge the networks.
