Hi Kevin,
So, do you have a single data request? Or do you have multiple discrete
data requests?
I'm asking because I have a number of discrete requests and I am getting
some with no problem, but not others.
Also, you mention the latency -- can you confirm that you are seeing
latency on your end but no latency in the upstream queue?
Lastly, my problems did not seem too bad until 11/04-2340 (from MRMS OPS).
I have not looked closely at prior data for latency.
