[OOL] Possible Routing Issue?

Hello,

I am looking at a possible routing issue from the Cablevision network to a Rackspace datacenter located in the Dallas, TX area. I have always gotten terrible upload speeds from our office to this datacenter, usually about 150KB/s on average. I had Rackspace check out on their end and they do not see any issues. So I ran a traceroute today and this is the result:

Tracing route to photocubbie.com [174.143.22.100]
over a maximum of 30 hops:

1 7 ms 10 ms 9 ms 10.240.165.105
2 8 ms 7 ms 8 ms 67.59.244.5
3 12 ms 10 ms 11 ms rtr2-ge1-15.mhe.prnynj.cv.net [67.83.252.133]

14 63 ms 59 ms 61 ms mail.photocubbie.com [174.143.22.100]

Trace complete.

At hop 7, it looks like packets are being routed to a telecom company in Sweden. I contacted tech support but they are claiming they are not responsible for packets once they leave the cablevision network. My question is: Isn't the CV router at hop 5 the one sending the packets to telia.net? I ran a traceroute from my house which is Timewarner and the trace stays in the US. I am assuming the slow upload speeds are a result of this routing. Can anyone provide any insight on this?

Thanks,

Ron

Unlikely it is going to Sweden and back, the times are way too low for that. Telia has backbone in the USA. The route times do not indicate a routing problem. 150 KB/s would be around 1mbps assuming you are using the correct B for Byte and not b for bit. Which OOL do you have normal or boost/plus.

Thanks for your reply- I have Boost Plus service. I am using scp on a linux server to copy a file- it's reporting about 120KB/s and is going to take about 24 hours to copy up a 12GB file.

Thanks,

Ron

The hop names give you a clue as to where it is. "Ash" on hops 7 and 8 stand for Ashburn, VA., "Dls" is Dallas, TX., "Dfw" is Dallas-Fort Worth, TX.

Thanks for that info- I googled Telia and the IP in the trace and was seeing that IP over in Sweden, so I assumed there was a routing issue. That clears it up. I am sure there is overhead using scp, so 140KB/s is as good as its going to get (about 1Mbps up).
