OK.  Which images were you unable to access?

Since the current time is 16:32 UTC, I am assuming that you had problems
accessing images between 18 and 20 UTC yesterday, July 21.  Based on
this, I looked to see what images we received during this time interval:

IMGLIST GVAR/ALL.ALL DAY=202 TIME=18 20
Image file directory listing for:GVAR/ALL
 Pos Satellite/         Date       Time      Center   Band(s)

 243  G-15 IMG      21 JUL 19202  20:00:00    26  137 1-4,6
IMGLIST: done

Not knowing which coverage (FullDisk (FD), CONUS, Northern Hemisphere (NH),
etc.) you are referring to, I examined our ingest status logs to see if there
were _any_ problems indicated for the 18-20 UTC time period yesterday, but I
did not see any problems.  This strong suggests that if images you were 
expecting
were not available, then they were not sent in the GVAR rebroadcast that we
ingest.

Further examination does show that we did have two periods of loss of
sync yesterday:

20:53:45 - 20:54:05
00:41:49 - 00:42:00

During loss of sync, no images are received.

Cheers,

Tom
