Hi Lucio,

re:
> Good Day, Can you please verify,   Our LDM feed port doesn't work from
> machine idd.unidata.ucar.edu  using port 388

I see two sets of LDM feed REQUESTs from the cmc.ec.gc.ca domain to
our top level IDD relay cluster, idd.unidata.ucar.edu:

ldm-data.cmc.ec.gc.ca  - HDS, IDS|DDPLUS, NEXRAD2
noaaport3.cmc.ec.gc.ca - NGRID, NNEXRAD (aka NEXRAD3)

In all cases, the latency plots for each feed for each of your
machines shows an extreme increase within the past 6-12 hours.
Since other sites are receiving the same feeds that your machines
are requesting with no slowdown, it is most likely the case that
some network path between your machines and idd.unidata.ucar.edu has
become excessively congested.  Unfortunately we have no control over
the network paths outside of our organization.  Your best bet is to
work with your networking folks to find out where the bottleneck is.

Also:

The latency plots for ldm-data.cmc.ec.gc.ca show that the clock
on ldm-data.cmc.ec.gc.ca is off by about 2000 seconds:

http://www.unidata.ucar.edu/cgi-bin/rtstats/iddstats_nc?NEXRAD2+ldm-data.cmc.ec.gc.ca

Please have your system administrator(s) investigate and correct
the clock problem on ldm-data.cmc.ec.gc.ca.

Request:

In the future, please include the name(s) of your machine(s) that are
having problems.  This will help us troubleshoot any problems more
quickly.

Cheers,

Tom
