For the past hour or so a number of sites that I have with Cogent have been unreachable. Also, I am unable to get through to their support line. Is anyone else seeing this? .myke lyons

Anyone else find it funny that of all the Cogent peering on that chart, only the Cogent to Level 3 link shows green? :-) David > -----Original Message----- > From: owner-nanog(a)merit.edu [mailto:owner-nanog@merit.edu] On > Behalf Of Ryan A.

Take a look at this: http://scoreboard.keynote.com/scoreboard/Main.aspx?Login=Y&Username=public&… I just got off the phone with Cogent. They said there was a fiber cut in the eastern-US. The representative did not have specific details. They said either in the NY or DC area.

They've got something going on, we've got about a 25% drop in our outbound Cogent traffic at about 9:45 AM EST.

Hello, This is Internet Initiative Japan (IIJ/AS2497) Network Operations Center from Tokyo, Japan. IIJ has started advertising 125.30.0.0/16 from AS2497/IIJ. Unfortunately, it seems that several ASs are filtering this route. Could you confirm that your latest filter permit 125.30.0.0/16? If it is denying the route, we hope you will update the filter to accept our new block. We have set an equipment at 125.30.127.1 for your conectivity check. If you confirm that you are able to access 125.30.0.0/16, you can ping and traceroute to 125.30.127.1. Recently, APNIC/JPNIC assigned 125.30.0.0/16 to IIJ.
