OK, thanks.

Follow-up question:

- what is 'hostname' defined as in your LDM registry, ~ldm/etc/registry.xml

OK.  Deleting and remaking the LDM queue will result in the most recent hour
of data being sent on all REQUESTs, so indicated latencies being large is no
unexpected.  Let's see what happens when things go to a steadier state.

What we didn't know until you sent us the output from 'ifconfig' is if your
machine had multiple interfaces and the routing to/from other upstream feed
sites was different than it is to/from us.  We now know that this is not
the case.

Again "for the files": other sites being fed from the same idd.unidata.ucar.edu
real server backend machine are not experiencing high latencies for the
same feeds as your machine.  This tells us that there is nothing fundamentally
wrong with the particular backend machine or its connection to the network.

Last question:

Is it possible that OU turned on an intrusion detection package like Palo
Alto?  These kinds of packages can be setup to inspect things on a per
connection basis.
