Hi Mike,

re:
> Clarification:  I meant forward lookup still points to old IP

Yup, got it.

I see that vulcan.sjsu.edu is now feeding from the new idd.unidata.ucar.edu.
Can I assume that all SJSU LDMs have been restarted and their REQUEST(s)
to idd.unidata.ucar.edu are now aimed at the new instance of this cluster?

On a related note, I just noticed that vulcan is redundantly REQUESTing
NEXRAD3 data.  Here is a snippit from the LDM utility 'uldbutil' that
shows the redundant REQUESTs:

11271 6 feeder vulcan.science.sjsu.edu 20190822000101.735282 TS_ENDT {{NEXRAD3, 
".*"}} primary
36386 6 feeder vulcan.science.sjsu.edu 20190822042436.255196 TS_ENDT {{NEXRAD3, 
"^SDUS5."}} primary

There is no need to do a REQUEST using the pattern "^SDUS5." when also
doing a REQUEST for ".*" (everything).  Since both REQUESTs are in primary
mode, the net result is you are simply using more bandwidth that you
need to use.

I have not checked other SJSU feed REQUEST(s) to see if there are other 
instances
of unneeded redundancy, so I can't say if this is the only instance.  If you
find other instances, it would be wise to remove them to lessen the bandwidth
that is being used both on your and on our ends.


Cheers,

Tom
