Users of Unidata services please note:
There will be a disruption of service for users of some Unidata managed
LDM/IDD and McIDAS ADDE instances this coming Saturday, December 15th,
beginning at 8:00 AM MST and lasting up to 6:00 PM MST. This disruption
will be similar to the ones experienced on November 10th and December 1st.
lead.unidata.ucar.edu (which is also know as hrrr.unidata.ucar.edu)
will be unavailable during the entire outage, so sites that use this
machine for McIDAS ADDE-served data and the NOAA/GDS HRRR LDM/IDD feed
should be aware of the likely interruption to their data processing:
- users pointing at lead.unidata.ucar.edu for ADDE served datasets
should change to point at adde.ucar.edu.
- unfortunately, there is no backup machine for the NOAA/GSD HRRR data
relayed by the LDM off of lead.unidata.ucar.edu
Also, it is possible (but we believe unlikely) that other services
could be affected by Saturday's outage. The services that could be
affected are:
LDM/IDD:
- idd.unidata.ucar.edu users should institute redundant REQUEST(s) or
failover to iddb.unidata.ucar.edu
McIDAS ADDE:
- motherlode.unidata.ucar.edu users should point their ADDE
requests to adde.ucar.edu are routed to different machines as the
need arises
TDS:
- a separate notice has already been sent to TDS users
The following is the internal NCAR/UCAR notice that we received about
the upcoming outage:
