20030226:ASU failover sites - traceroute files

Hi Nancy, 

What version of the LDM are you running...?

Unless really old..pre 5.1, MCIDAS should still alias to UNIWISC (the new
name for sat imagery)

Try placing the requests on 3 lines, I was going to have you do this to
nimbus as wellas it can decrease latencies..

so try:

request UNIDATA ".*"            thelma.ucar.edu
request NNEXRAD  ".*"            thelma.ucar.edu
request MCIDAS ".*"            thelma.ucar.edu

Then the old start and stop..

The allows for you are there..

Try a notifyme -vl - -h thelma.ucar.edu -f MCIDAS -0 1500

and like wise for the other "feedtypes" to see if you are allowed.

If allowed you will see prods scrolling by..

Keep me posted!

-Jeff
