Hi,

re:

This would have been incorrect since Karl was in COSMIC, not Unidata, and
we are the ones who manage these top level IDD relay clusters.

re:
> I suspect that this request would now be handled by address@hidden.

Correct.

re:

Since there is both forward and reverse DNS for gsddata.esrl.noaa.gov,
and since reverse DNS resolves to a '.gov' address, you should already
be able to REQUEST the feed(s) you want/need from either/both
idd.unidata.ucar.edu and iddb.unidata.ucar.edu.  You should test
this as follows:

<as 'ldm' on gsddata.esrl.noaa.gov>

notifyme -vl- -f ANY -h idd.unidata.ucar.edu

A line that looks like:

20200908T181623.217700Z notifyme[136777]            ldm5_clnt.c:forn_signon:294 
        NOTE  NOTIFYME(idd.unidata.ucar.edu): OK

will be the verification that your machine is ALLOWed to REQUEST feeds
from idd.unidata.ucar.edu (and the same will be true for iddb.unidata.ucar.edu).

re:

OK, sounds good.

re:
> Our target date to have this migration completed is Sept 30, 2020.

I think you will find that you can make the switch immediately.

re:

> Thank you,

No worries.  Please let us know if you experience any problems.

Cheers,

Tom
