Hi all.
NERSC, the supercomputer center where our servers host the Legacy Survey website and other services, will be doing power equipment maintenance and performing major upgrades to their facility, computing systems, file systems, storage systems, and NERSC services and websites.
During this 6+ day period, the Legacy Survey sites will be unavailable for users beginning on January 27, 2025, 9:00 am PDT, effective until February 1, 2025. 10:00 PM PDT. An extended outage is likely. This outage will affect the following services:
- Legacy Survey Website (www.legacysurvey.org)
- Legacy Survey Sky Viewer (Legacy Survey Sky Browser)
- Fastspecfit
- Siena Galaxy Atlas (sga.legacysurvey.org)
- unWISE (unwise.me)
- Other websites or projects that rely on the abovementioned services will be unavailable or degraded during this time.
Services that will remain up during this time:
- Legacy Survey Discussion (discuss.legacysurvey.org) ~ Externally hosted
- Google Forum ~ Externally hosted
- GitHub pages ~ Externally hosted
A “mirrored” version of the viewer will be available, as it’s hosted on AWS but has limited features and functionality: viewer.legacysurvey.org.
The outage will only happen at the end of the month. During this time, users are strongly encouraged to plan accordingly; monitor this page for updates as they become available. We are sorry for the inconvenience.
