Ah, so perhaps not a good test.. I'll set it back to a 5-way split and see how it looks tomorrow.

[cid:169e96b8c936351386f3] Prior to whatever is going on to cause this, I don'r recall ever seeing lags this large with a 5-way split. It looked much more like the left hand side of this graph, with small increases in lag with each 6 hourly model run cycle, but more like 100 seconds vs the ~900 that I got this morning. FYI I am going to change back to a 10 way split for now.

I concur with Art and Gilbert that things appear to have gotten better starting with the failover of everything else to Boulder yesterday. I will also reconfigure to go back to a 5-way split (as opposed to the 10-way split that I've been using since this issue began) and keep an eye on tomorrow's 12 UTC model run cycle - if the lags go up, it usually happens worst during that cycle, shortly before 18 UTC each day.

Anyway, I agree with Gilbert's assessment. Things turned real clean around 12Z yesterday, looking at the graphs. I usually look at flood.atmos.uiuc.edu<http://flood.atmos.uiuc.edu> when there are problem as their connection always seems to be the cleanest. If there are even small blips or ups and downs in their latencies, that usually means there's a network aberration somewhere that usually amplifies into hundreds or thousands of seconds at our site and elsewhere. Looking at their graph now, you can see the blipiness up until 12Z yesterday, and then it's flat (except for the one spike around 16Z today which I would ignore): [cid:169e96b8c93f456b1e51] Our direct-connected site, which is using a 10-way split right now, also shows a return to calmness in the latencies: [cid:169e96b8c93f456b1e52] Prior to the recent latency jump, I did not use split requests and the reception had been stellar for quite some time. It's my suspicion that this is a networking congestion issue somewhere close to the source since it seems to affect all downstream sites. For that reason, I don't think solving this problem should necessarily involve upgrading your server software, but rather identifying what's jamming up the network near D.C., and testing this by switching to Boulder was an excellent idea. I will now try switching our system to a two-way split to see if this performance holds up with fewer pipes. Thanks for your help and I'll let you know what I find out. Art Arthur A.
