Did Cornell have any response to your inquiries..?

Yes, if anyone above you does not report, the whole limb drops off the
map..we are working to resolve this issue so you can "see" a better
picture of current status.

We have not set-up a failover scheme for NNEXRAD or FNEXRAD since it
follows a different topology than the other prods, what we did implement
was an allow *.edu for NNEXRAD from the top NNEXRAD sites:

http://www.unidata.ucar.edu/projects/idd/nexradFeed.html

Most have left it in, so you can feed from any of the top tier sites if
your standard feed is not performing.

try

notifyme -vxl- -f FNEXRAD -o 3600 -h snow.nrcc.cornell.edu

and check other hosts than snow..

Sorry about your latencies, things have been pretty smooth over here, but
I know that is no solice for your situation.

Please keep me posted if problems persist and we can explore
alternatives..

I will be on vacation next week, but if the question goes to
address@hidden it will find an appropriate individual.


Thanks!
