Re: Chicago Routing is WACKED! This needs to be fixed ASAP!

The routing through Quest on the 3rd and 4th Hop:

4 chx-edge-01.inet.qwest.net ( 54.999 ms 11.455 ms 10.802 ms
5 cer-core-02.inet.qwest.net ( 11.305 ms 11.447 ms 10.835 ms

has not changed muched, i'm still getting 30-40 ms connecting to Local Chicago Servers from chicago, where as for the past 5 years i've been getting 8-12 ms ping time. this is really got me upset on this awful routing. If quest using interleaving or error checking or something, thats the only things that jumps ping times up like this.

There was a problem with the Cogent network yesterday that seemed to trickle down to Cogent's other peers. One of the peers that had problems was Savvis.

After noticing weird Cogent routing problems yesterday I checked with internet health report. I have not seen that much red since the level3 fiasco.

I still don't know what happened out there with Cogent. On the 14th of February, the fiber had become severed in New York.

The word on the street here in the Chicago colo market is that Cogent might have the best prices, but at the expense of reliability. Call this an extreme example.

I'd like to know what freak of networking caused what should have been a 16 block hop from CHX to Equinix to suddenly head for New York, going right past Equinix along the way. That area is crazy-full of fiber. That is truly screwy!

That increase on hop 4 doesn't indicate it problem, it just indicates that Qwest's router is likely deprioritizing ICMP ping packet requests (which is the way many routers are configured). Does the full trace show higher than normal latency at the destination?
