Pete,

re:

>(18:55 UTC). I have failed over to idd.unidata.ucar.edu for now.

It appears that the problem is a strange interaction between your request
pattern:

UNIWISC|HDS|DDPLUS  ".*|!^SDUS5.*"

and a code modification in LDM 6.3.0 that tries to "fix" incorrect
patterns on the server side (the LDM on unidata2 was upgraded from a
very old distribution (6.0.14) to the current release (6.3.0) by me
today).  Since I saw no 'Denying' connection messages in the
~ldm/logs/ldmd.log file, and since I verified that data was flowing to
UPC machines feeding from unidata2, I expected that everyone was
getting data OK.  Apparently you are the only downstream that saw any
effect.

Your feed request is apparently trying to get everything except
products whose headers start with SDUS5.  Since products with headers
of SDUS5 are NEXRAD Level III products, and since your request line
does not include NNEXRAD data, the simplest fix is for you change your
request line:

request UNIWISC|HDS|IDS|DDPLUS  ".*"    unidata2.ssec.wisc.edu

 -- or --

request UNIWISC|WMO     ".*"    unidata2.ssec.wisc.edu

 -- or --

request UNIDATA ".*"    unidata2.ssec.wisc.edu

Please correct your ldmd.conf request line; fail back to unidata2; and
let us know that you are once again getting the data you want.

Cheers,

Tom Yoksas

Tom,

I think that was in there from long ago when the IDD ingest switched over to
NOAAport from the original satellite feed. At any rate, I've changed it to
just UNIDATA ".*" and data seems to be flowing just fine.

Thanks,

Pete
