Follow-up: They switched to the BNCF at 14:15Z this morning. I i'm not seeing
missing satellite images, but I am seeing a huge number of re-transmits and
duplicates that the LDM is rejecting at AllisonHouse and COD. A contact I have
at NCF emailed me to check on it, and I have given him log samples so he can
see what's going on.
