20090721: dados do tigge



Hi Doug, Manuel, et. al.,

While I don't have any insight into what is causing the problem,
I can offer my hunch:  it is a routing problem in NLR.  I say
this because a traceroute to a Unidata user site hangs at the
NLR node in Denver:

traceroute tornado.geos.ulm.edu
traceroute to tornado.geos.ulm.edu (198.202.242.22), 30 hops max, 40 byte 
packets
 1  flra-n140 (128.117.140.253)  1 ms  0 ms  0 ms
 2  tcom-gs-1-n243-80.ucar.edu (128.117.243.85)  1 ms  1 ms  1 ms
 3  nlrb-frgp.frgp.net (192.43.217.113)  1 ms  1 ms  2 ms
 4  frgp-nlr.frgp.net (192.43.217.138)  5 ms  2 ms  13 ms
 5  hous-denv-82.layer3.nlr.net (216.24.186.27)  31 ms  31 ms  31 ms
<hang>

If I knew who to call, I would get on the horn to NLR (or I2?) to
report the problem.

Cheers,

Tom
