 scoobyPremium join:2001-05-01 Schaumburg, IL kudos:1 1 edit | reply to timisdaman You sure do goto Germany. I wonder was something broke on the net when you did that traceroute or if it is always like that for you. |
|
 | I did that traceroute 10/10/2005. I noticed it because I play a game on that server, and my ping was unusually high. It was not always like this. I first noticed it last week. No idea what happened. |
|
 | reply to timisdaman here it is. found it. the one right after the german router:
38.112.93.50
Performance Systems International Inc. COGENT-NB-0002 (NET-38-112-0-0-1) 38.112.0.0 - 38.119.255.255
this is most likely a side effect of poor crisis management when level3 cut off cogent. they most likely routed through germany in order to keep their servers online. |
|
 | heh, i'm lost... what do you mean "when level3 cut off cogent"?
thanks to everyone for the replies, btw  |
|
 scoobyPremium join:2001-05-01 Schaumburg, IL kudos:1 | reply to timisdaman Yeah spaz.com is hosted on Cogent. Most likely AT&T is being a bully to them. If you know the admin, they should be able to get cogent to address the issue. Most likely that is the closest point of peering between Cogent and AT&T so the traffic goes there.
This is one of the big negatives Comcast has by being single homed to AT&T. If they had a connection to Cogent (or any of the Cogent friendly providers) in your area you'd have killer ping times to that server. Hopefully this will change with SBC buying AT&T. |
|
 | Thanks for the info. I've managed to get around this by connecting to my school's (Boston University) VPN. I actually get better pings with VPN than before this problem. This is weird for me, as in my previous experience with VPN (Boston College), my connection was much slower. |

-- Norman ~Oh Lord, why have you come ~To Konnyu, with the Lion and the Drum |
|
 | I agree with NormanS. There is no possibility that the IP in question is anywhere other than the east coast. Since the minimum observed ping from your location is 15 ms, it has to be within 1,000 miles assuming that there are no delays in any router. Looking at the latencies for earlier hops, it sure looks to be in NYC just like its URL suggests. |

1 edit | reply to timisdaman Not according to the ping times. You have 25ms to 217.239.40.78, but you have 89ms to 38.112.93.50. What law of physics permits electrons to pass though a trans-Atlantic cable in less time that to pass through wire/fiber along the U.S. east coast?

Re: [Connectivity] Tracrt reveals I go through Europe umm guys do you understand how fast light travels? Germany is not far from the US at all. Ping time are mostly made up from equipment, not distance.
think about this. You can ping California from New York in 20 ms (I'm saying 20 because that's what I was getting in New York to some servers in Sandiago). How how can you say that germany would require at least 200ms? It's not 10 the distance.
I'm GUESSING it wouldn't take more than 20 to 50 ms to cross the atlantic on fiber. That even sounds high, but I don't know.
Do the math though it should be simple. I don't feel like putting the thought into formulating it. |
|
 | The math is simple. 15 ms per 1000 miles of fiber. The minimum ping for a path between NY and CA is typically 80 ms, of which ~50 ms comes from the distance. NY to the continent is typicallly 200 ms. |

C:\Documents and Settings\David Adkins> #1 is to the server you are tracing(80ms). #2 is to Pipex.net(UK ISP)
I'm in California, no way I can hit the UK(or Europe) at under 150ms(today is a "Good Day").

Re: [Connectivity] Tracrt reveals I go through Eursaid by dhgdfg :
umm guys do you understand how fast light travels? 186,000 miles per second in fiber? I don't think so. Look up "index of refraction". In any case, if that were the primary factor behind latency, there would be no difference between the latency of dial-up and HSI traceroutes. But Sam Spade tells an interesting "Tale of Two Traceroutes":

The 'SanJose1' in the first is San José, Calif. The 'sntc01' in the second is Santa Clara, Calif.; I can assure you that, in terms of the speed of light, the two cities are effectively on the same pinpoint.
P.S. I have to brag a little about figuring out how to manage Internet connectivity through two different routers on the same LAN segment. ;)
