GLADE file system status
Individual files are removed from the /glade/scratch space automatically if they have not been accessed (modified or read, for example) in more than 90 days. That retention policy is subject to change as described in this Daily Bulletin item.
Queue activity and login node status
System maintenance
CISL makes every effort to perform routine maintenance without taking systems out of service. If downtime is required, routine system maintenance is performed during the times shown. Urgent updates are scheduled with as much advance notice as possible. The schedule of planned downtimes for the week is announced in the Daily Bulletin.

System news and updates
Daily Bulletin
You can read the "Daily B" online or in your email for reports on system news, changes to the CISL environment, and scheduled maintenance periods for major CISL resources.
All new CISL email addresses ([your UCAR username]@ucar.edu) are added to the Daily B mailing list automatically. You can change your Daily B preferences, subscribe, or unsubscribe online.
For questions or more details about Daily B items, email cislhelp@ucar.edu or call 303-497-2400. To submit items or information to the Daily B, contact hdt@ucar.edu.
Notifier
The Notifier service provides a near-real-time feed of system status changes and other updates, so it is the best way to learn about status changes, particularly unscheduled outages. You can also log in to check the calendar.
New users are subscribed automatically to the “CISL Status” Notifier list and receive notices about NCAR supercomputers, storage systems, and support services. The CISL User Services Section manages notices posted to the CISL Status list to ensure that they are relevant to users.
To fine-tune your Notifier subscriptions, log in to Notifier. Keep in mind that if you unsubscribe from all Notifier lists, you will not receive timely system status information. If you opt out of the CISL Status list, we strongly recommend subscribing to at least some of the following lists: Yellowstone, Geyser and Caldera, HPSS, and HPC Support Services. (Many other lists are targeted primarily at UCAR staff or UCAR system administrators.)
