[IDD #QRO-177042]: Seeking Conduit data

Hi Ruth,

Sorry for the tardy reply...

You can feed CONDUIT data from idd.cise-nsf.gov for the time being.  We
will, however, want to get Penn State to allow you to feed CONDUIT from
their new toplevel IDD relay cluster.  Please send a note to the LDM/IDD
contact at Penn State requesting that your machine be allowed:

"Art Person" <address@hidden>

OK, your machine is not allowed to request CONDUIT data from gusher.

This shows that you could feed from bigbird.tamu.edu.

Not allowed.

Please see above.

The best thing to review is the hourly volume statistics for CONDUIT
while remembering that the GFS data dominates the CONDUIT volume:

Unidata HomePage
  Software -> IDD
    Real-Time IDD statistics
      Statistics by host

Take a look at CONDUIT volumes being received on idd.unidata.ucar.edu:


Please be advised that there have been problems in the CONDUIT datastream for
the past couple of days (high latencies).  This problem is actively being 
so you may want to hold off on setting up your CONDUIT feed until they are 
This is not to say that you should hold off on contacting Art Person to get PSU
to allow you to feed from them.

> Thanks for your help,

No worries.
