So here's a followup to the previous message...
I chatted with Pat Finnegan, who runs pollux.itap.purdue.edu and
castor.itap.purdue.edu, Purdue's top-tier machines. Based on the rtstats data,
castor seems to be the only one with problems. Pat has switched castor to feed
from pollux instead of from the NWS. This seems to have cleared up the latency
problem. Pat mentioned he's been trying to get CR to open up the firewall for
a new machine (castor.rcac.purdue.edu), but it has not been done yet. So my
hypothesis is perhaps the CR firewall is doing funny things to packets destined
for castor.itap.purdue.edu. I'm not sure what those funny things might be, but
it at least fits the situation.
So I guess the plan for now is to let pollux do all of the ingest from the NWS
and then both pollux and castor will serve the data to downstream sites. I
won't speak for Pat as to how long this arrangement might last, but everyone
should be getting their data on time now.
