Slow downloads from NOMADS also for you?

Slow downloads from NOMADS also for you?

Post by oib » Mon Apr 03, 2017 2:47 pm

On March 2017 NCEP NOMADS front-end servers have experimented severe troubles.
And this was repeatedly confirmed by NCEP.

In the last week and also today I'm continuing to observe tremendous slow download times for GFS 0.25 Hourly data using the grib filter tool (-> http://nomads.ncep.noaa.gov/cgi-bin/filter_gfs_0p25.pl).

Because the last week I changed my internet provider, at this point I'm a bit confused: I can't really understand if the problems still depend on NOMADS servers or if the slow download speed is due to a poor (and unexpected) quality of service from my new internet provider.

If you also are a NOMADS grib-filter user, could kindly let me know if you're still having problems?

Thanks in advance ;)

Hello,

From my logs - fastest downloads on particular installation take ~7 minutes to complete. On 30th March I had almost 40 minutes download time on one run. Currently, around 12 minutes. So, not horribly slow, but it was faster on best days. These are my stats from March 1st up to today:

I apologize for the incorrect assertion, and I correct: download problems are caused by NOMADS servers that serve regional tiles (grib filter).
NCEP help desk confirmed to me that problems started on March 28 and today still exist.
