Hi Robert and list,
Yes, Unidata is NOT operational, we deliver best effort.
Currently best effort is significantly better than 10 minute latency
on either the CONDUIT or NEXRAD2 feeds..
NEXRAD2:

CONDUIT:
http://rtstats.unidata.ucar.edu/cgi-bin/rtstats/iddstats_nc?CONDUIT+oliver.unidata.ucar.edu
..as you can see latencies are in the 10-15 second range for NEXRAD2, and
about 30 seconds for CONDUIT
Blair,
Did you implement the suggestion from Steve Emmerson regarding the:
-close
from the PIPE command?
Cheers,
Jeff

Unidata certainly doesn't guarantee operationally timely access to CONDUIT,
and it should not either with Level II data distribution. They are both just
too huge to assure that. I'd like to see a response from Unidata on this.

Sorry, I am not dissing NSSL at all. I just thought that since Blaire was at
a dot com address that there might be a better routing for him. If NSSL says
that anyone that is somehow allowed access regardless of .com or .edu staus
can get 20 second max latency then I am surely dropping out of this
conversation.
It's all pretty confusing since Unidata has always distanced themselves from
anything operational..and it surely is a participant in the Level II feed.
Getting back out of this hornet's nest..

I also just checked the IRADS data monitoring page. Only members have
access to it, but it keeps an avg. and max latency for the Level II data.
Scanning the monitoring page the maximum latencies I see at IRADS is less
than 20 seconds, and in most cases, less than 5 seconds.
I can tell you at NSSL, we are very sensitive to latencies and would be
well aware of 10 minute latencies in our realtime WDSSII system.
