Steven,
It appeared to me that the suomildm1.cosmic.ucar.edu clock was about
6-7 hours off a while back....and data would start flowing again after
restarting the LDM in about 7 hours when the real world time
caught up. We don't get stats from that computer so I can't verify, but looks
like a UTC vs local time zone problem. Perhaps COSMIC can double check that
system's clock. Note that the clock on the machine creating the data looks to be
correct, and that soumildm1 is just a relay of the feed.
In the worst case on a long holiday weekend, I think you should start seeing
data again without doing anything in about 7 hours.
