Hi David,
Theoretically, you should be able to feed NNEXRAD from any of the second
level routing machines...they should all have an allow *.edu NNEXRAD.
Soooo, I will make the changes to our documentation here regarding that
feedtype and go with you feeding NNEXRAD from:
flood.atmos.uiuc.edu
and remove you from Penn State.
I will fire off an e-mail to David Wojtowicz to see if we can use his
machine as your failover for the FOS feeds and cc you...Hopefully he will
be amenable.
I will verify if it is flood or squall for FOS feeds...
Thank you,
-Jeff
