Re: [conduit] Large CONDUIT latencies to UW-Madison idd.aos.wisc.edu starting the last day or two.

All,

Something bigger than just CONDUIT users occurred on the 19th. We had numerous users of other servers complain of similar drops in transfer rates. A few of them were also able to move downloads to a new location where speeds were normal. We believe that this issue was outside of NCEP due to that reasoning. Having said that though, is anyone still seeing abnormal rates?

In the hopes of keeping the ball rolling on this issue before I quit for the day, I have another screen cap to share of MTR running from one of my colo boxes to ftp.ncep

notice that latencies running along the hurricane electric backbone are fine, then quickly pick up an additional 20ms from the hop, but packet loss does not begin until the handoff between gigapop and ncep itself, which also displays the highest standard deviations along the route..

 

hope everyone has a good weekend J

 

cheers,
