Our data feed has been lousy the past few days.  I did notice that 
navierldm was down for a while and failed over that day.  I also upgraded 
to the newest release of ldm.  No Joy.  

Ping generally reports 10-25 percent packet loss.

Traceroutes from my end don't look bad:

cirrus:/home/ldm> traceroute navierldm.meteo.psu.edu

But many products don't complete in the  required time, e.g.:

I wonder if there's anything up at PSU that might be affecting this?


Thanks
