[Support #QNF-376251]: [conduit] Missing GFS grids on CONDUIT this morning?

Hi Pete,

re:

I noticed the much lower volume of data in the CONDUIT feed for the
15 and 16 UTC hours, and a higher volume than usual for 17 UTC.  We were
not aware of any planned partial outage.

we (Unidata) do not have any idea.  A message we received from Dustin 
Sheffler on another CONDUIT related topic (including the need to
fix the clocks on the NCEP top level IDD sources for CONDUIT) made
no mention of an impending outage.

re:

I was monitoring CONDUIT volumes because we are upgrading all of our
LDM instances to the version Steve released yesterday, LDM-6.13.12,
and we do not cut over to new LDM releases during CONDUIT data
maxima.

Cheers,

Tom
