Re: Extreme Slowness

We peer with UUnet and Telcove (now L3 and being "assimulated")
Latency across Telcove has been terrible (not just routers on the path with higher than norm latency, but latency all the way to the endpoint)
I have personal opinions as to why the latency is so bad, but until I can prove something I'd rather not say anything in public.
Some examples : 72.30.33.194 is 60.8 ms away via uunet, it is 109ms away via Telcove. www.level3.com via uunet is 30ms away, via Telcove it is 55ms away.

Trace to level3.com via UUNet

Adam,

Because of contractual issues it makes it very hard for me to participate on this list hence the vague original post. I was just asking a general question to see if anyone else was having issues. I have peering points with Broadwing(now level3), Sprint, AT&T and MCI(now Verizon) that I can test for throughput from.
