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? Hi Carissa J From our Amazon location in VA, everything is fine as it was on Friday… From our colo facility, packet loss is still shown via 140.90.111.36, which is the hop from gigapop to ncep.. here is an MTR showing the packet loss: http://drmalachi.org/files/ncep/he-ncep.2016.02.22.jpg Notice that since our colo is directly on the Hurricane Electric backbone, there are only a few hops to get to the ncep server, and pings only jump once they reach gigapop. Here is a screen cap of current download speeds for 0.25deg gfs from the ncep server to our colo: http://drmalachi.org/files/ncep/he-ncep.wget.2016.02.22.jpg In order to ensure proper delivery, we have setup a push / pull from our amazon box to the colo, but most people probably won’t have that flexibility.. The issue appears to potentially be related to packetfiltering and / or redirection / funneling via certain routes, but that’s just a guess J Happy Monday J Cheers, --patrick ------------------------------------------------------- Patrick L.
