Hi Doug, Manuel, et. al.,
re:
We're currently having connectivity issues between ECMWF (tigge-
ldm.ecmwf.int) and NCAR (dsspub.ucar.edu), CMA (tigge-cma-
ncar.cma.gov.cn)
and NCAR (dsspub.ucar.edu), and ECMWF (tigge-ldm.ecmwf.int) and
Brazil ( tigge-ldm.cptec.inpe.br ). If you have any insight into the
problem, it would be greatly appreciated.
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
-ECMWF has been unable to ldmping or retrieve data from NCAR's ldm
server since
~July 10. No recorded changes have been made to NCAR's server during
this period (Although I did restart ldm multiple times
yesterday to see if that would help out).
I'm trying to ldmping dsspub.ucar.edu I get:

ECMWF see's the same ldmping problems to Brazil (but has been able to
retrieve data).:

I performed an ldmping test from dssingest.ucar.edu to

and get a similar error message,
yet have no problem retrieving data from dsspub:

I'm puzzled because we don't miss data from CPTEC since 14th July
(we miss 1 field for one cycle). Perhaps we manage to get the data
via other archive centers. Do other Archive Centres (Doug, Xiaofeng
Bian) have the same problems with CPTEC's LDM ?
Cheers,
Manuel

Hi Manuel,
Would you, please, do a ldmping on mopora.cptec.inpe.br <http://mopora.cpte
c.inpe.br
?
We're still trying to figure out the possible problem in our link.
Again, we apologize for the inconvenience.
Thanks,

Hi Waldenio.
I think your LDM is still unreachable from our machine:

Could you, please, include Baudouin in your e-mails ? I'll be
away
for some days...

Hello Manuel,
Are you receiving the CPTEC's Tigge data ? I cant see the

Thanks,
