This reminds me of those daze when they did experiments with spiders. They dosed them with LSD and took pictures of the webs they wove afterwards. I've intentionally deleted the end-points. I also sent this to both Qwest and SPeakEasy over two weeks ago. These routes are persistent.

It's not their fault (not counting poor decisions of where to peer or buy transit), it's INAPs.

Speakeasy uses InterNAP for transit... Though why a DSL provider would pick a company who's model for optimizing traffic is far more useful outbound then inbound is beyond me. Maybe INAP gave them some $200/meg transit to try and stay in business...

---Finally gets to QWest (used to be USworst ... may still be) but still hasn't left SF

And InterNAP uses QWest for transit...

Semi reasonable on qwest's part... Can't afford to peer with everyone everywhere can you... :P

Well you did find some broken DNS at AboveNet... (or else they're trying out some new IP over teleportation technology)... From tracerouting around a little bit it looks like that hop 13 is actually an OC48 between core1 and core4 in sjc2.above.net.

Over to another facility in San Jose...

Coming back seems to be much more intelligent (less drifty);

Well who's to say that InterNAP didn't find a better path... It's always possible that using Qwest and peering with AboveNet in LA is better then using Sprint and peering with AboveNet in the bay area... That being said, it's more likely then not just minus points for the ASimilator...
