The NCAR bi-annual facility shutdown is this coming weekend.

Most systems will be down from 6 AM to 6 PM on Saturday, 4 APR 2013. This includes the ESG site for downloading NCL, PyNGL, and PyNIO, and the NCL and related websites.

Other systems and networks may be shutdown or unavailable for a longer period. Here is the full text with more information:


NCAR's Mesa Lab data center will be undergoing significant electrical work during the semi-annual power-down scheduled for Saturday, April 20, from 6 a.m to 6 p.m. While NWSC will not be directly affected, users will notice several effects of this maintenance period:

* During this outage, HPSS will be taken out of service to eliminate the possibility of errors or confusion while the Mesa Lab tape libraries are powered down.

* Some YubiKeys and CryptoCARDs will not work, including many of those belonging to UCAR staff, while the NCAR RADIUS server at Mesa Lab is out of service. The RADIUS server is slated to be returned to service as early as possible after the maintenance work has been completed.

* CISL's GridFTP service (and GlobusOnline) will be unavailable from 5 p.m. April 19 through 12 p.m. April 21. The GridFTP service is scheduled to be migrated to NWSC, but not until after the power-down.

* CISL's license server, which enables software including Matlab, IDL, and Fluent to be used on Yellowstone, Geyser, and Caldera, is also in the process of being migrated to NWSC. Licensed software may also not be usable from 5 p.m. April 19 through 12 p.m. April 21.

* Finally, CISL user support relies on a number of services that will also be down, including the ExtraView ticket system, Notifier, email, and the CISL web site. The CISL Help Desk phone line, 303-497-2400, will still be available for urgent situations, but note that Saturday is outside of normal business hours.

Aside from these Mesa Lab-housed services, Yellowstone, Geyser, Caldera, and GLADE will continue to operate normally during the power-down. Users are encouraged to submit jobs to be run over the April 20 weekend, though users may need to work around the HPSS outage.
