i'm not seeing missing satellite images, but I am seeing a huge number of

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.</div>

I am going to try to kill two birds with one stone here.<br>

1. The GOES-16 missing tiles issue has been resolved when SBN/NOAAport is
sending their uplink via the ANCF and primary uplink. This problem was due to
multiple</span></p>
<p class="x_MsoNormal"><span style="font-size:11.0pt">issues, but they have
gotten them taken care of on the NESDIS side of things. They had a nagging
problem with channel 10, but that has been resolved (they had an issue at 14:10
with</span></p>
<p class="x_MsoNormal"><span style="font-size:11.0pt">a missing tile this
morning, but NOAAport was down for 5 minutes while they made expected changes
to the SBN this morning, and all channels had a glitch at that time).</span></p>
<p class="x_MsoNormal"><span style="font-size:11.0pt"> </span></p>
<p class="x_MsoNormal"><span style="font-size:11.0pt">2. Additionally, the
out-of-sequence packet issue when they are on the ANCF has been resolved, and
was determined to be an NCF issue.</span></p>
<p class="x_MsoNormal"><span style="font-size:11.0pt"><br>
But…<br>
<br>
When they are on the BNCF, and transmitting from their alternate uplink site,
they still experience out-of-sequence packets, numerous missing
products</span></p>
<p class="x_MsoNormal"><span style="font-size:11.0pt">that have to be resent
(we see a LOT of duplicate products here at COD when they are on the BNCF),
missing satellite tiles…and even missing satellite images.<br>
<br>
NCF is aware of the situation. Last week they switched to the BNCF for 3 hours,
and the problems were still there, so they switched back to the primary. They
are working on it.<br>
