Hi Pete,

I inquired about this a little bit ago, you weren't the first to notice
that.  The response was that it's a result of this planned change to ABI
Mode 4:
https://www.ospo.noaa.gov/data/messages/2024/01/MSG_20240104_1344.html

Normally what that does is only scan the FullDisk to give it 5-min
resolution, the Meso sectors and CONUS get turned off, but the CONUS domain
is cropped out of FullDisk and that still goes to SBN; CONUS GRB is another
matter however.  If you look at some other online satellite sites, the ABI
products for CONUS are still being made.  What I did NOT know is this mode
change effectively breaks the CIRA RGB CONUS products we transmit out.  So
we know those are down, as well as some of our GRB-derived products more
than likely.

>From that notice we've got about another 15 minutes or so, fingers crossed
it's back in short order.

Best,
-Mike
