Greetings,

It appears idd.unidata is unreachable again.  Has the same power issue happened 
once more?

Subject: [ldm-users] 20200709: idd.unidata.ucar.edu outage earlier today

LDM/IDD participants:

Earlier today, service from the top level IDD relay idd.unidata.ucar.edu
was lost for a substantial fraction of an hour.  The cause of the outage
appears to have been a power supply failure in a unit that provided
Internet connections in and out of the UW/NCAR NWSC (NCAR-Wyoming
SuperComputer center) where the idd.unidata.ucar.edu cluster is housed.
Since a fix to the problem had been anticipated to be fast, the outage
was not announced to the IDD community while it was in progress.

Impacts:

For sites whose LDM queues are large enough, the outage should not
have resulted in loss of data.  For sites whose LDM queues are "small",
there could have been a loss of some data.

Please send questions/comments to:
