Just an FYI the CONDUIT latency times continue to slowly increase. Unidata is seeing the same slowly increasing lags, so that suggests to me it is an issue with the source. I don't think we're actually getting data that much later, I think the clock has a slow drift on conduit.ncep.noaa.gov. We are not experiencing any real problems with this right now, but if the lag grows larger than 3600 seconds, I am concerned we will begin losing data, since (as I understand it) the ldm doesn't ask for data more than an hour old. Can you please have someone look into this at some point?

That is a very interesting and telling graph for a slowly worsening issue. We will investigate and let you know what we find. -Dustin On Tue, Jun 2, 2020 at 5:15 PM 'Pete Pokrandt' via _NCEP list.pmb-dataflow <ncep.list.pmb-dataflow@xxxxxxxx<mailto:ncep.list.pmb-dataflow@xxxxxxxx>> wrote: Carissa, Anne, Thanks so much for keeping us updated on these outages. FYI I think there is a slow clock drift on the CONDUIT source machine conduit.ncep.noaa.gov<http://conduit.ncep.noaa.gov>. I'm seeing the lags slowly increasing at my ingest site, and I see the same slow increase on conduit.unidata.ucar.edu<http://conduit.unidata.ucar.edu>. I don't see the same drift on data feeds from other sources. Maybe the conduit.ncep.noaa.gov<http://conduit.ncep.noaa.gov> isn't running ntpd to keep the time accurate? https://rtstats.unidata.ucar.edu/cgi-bin/rtstats/iddstats_nc?CONDUIT+idd-agg.aos.wisc.edu https://rtstats.unidata.ucar.edu/cgi-bin/rtstats/iddstats_nc?CONDUIT+conduit.unidata.ucar.edu [cid:17285ce99bacb971f161] Thanks, Pete <http://www.weather.com/tv/shows/wx-geeks/video/the-incredible-shrinking-cold-pool>----- Pete Pokrandt - Systems Programmer UW-Madison Dept of Atmospheric and Oceanic Sciences 608-262-3086 - poker@xxxxxxxxxxxx<mailto:poker@xxxxxxxxxxxx> ________________________________ From: conduit <conduit-bounces@xxxxxxxxxxxxxxxx<mailto:conduit-bounces@xxxxxxxxxxxxxxxx>> on behalf of Anne Myckow - NOAA Federal via conduit <conduit@xxxxxxxxxxxxxxxx<mailto:conduit@xxxxxxxxxxxxxxxx>> Sent: Monday, June 1, 2020 1:00 PM To: Carissa Klemmer - NOAA Federal <carissa.l.klemmer@xxxxxxxx<mailto:carissa.l.klemmer@xxxxxxxx>> Cc: support-conduit@xxxxxxxxxxxxxxxx<mailto:support-conduit@xxxxxxxxxxxxxxxx> <conduit@xxxxxxxxxxxxxxxx<mailto:conduit@xxxxxxxxxxxxxxxx>>; _NCEP.List.pmb-dataflow <ncep.list.pmb-dataflow@xxxxxxxx<mailto:ncep.list.pmb-dataflow@xxxxxxxx>> Subject: Re: [conduit] [Ncep.list.pmb-dataflow] NCEP CONDUIT Outage planned Hello, Wanted to let you know that the 6/3 outage has been moved to 6/8, same time .
