Announcement: Red Cloud 2 is launching November 25th, 2024. Watch for an email with migration details.

Globus downtime at 9:00am Central on Saturday, November 2, 2024 Globus services will be unavailable for up to 1.5 hours beginning at 9:00 AM US Central on Saturday, November 2, 2024 due to planned maintenance that includes database upgrades. During the downtime, the following will be impacted: All Globus services will be unavailable, including Auth, Transfer, Flows, Search, Timer, and Action Providers. Users will not be able to authenticate to applications that rely on Auth, including the Globus Web app, the Globus command line interface, third party applications and services, for example web portals that use Auth for user login or applications that use Globus services for data management. Transfers that are inflight when the downtime begins will resume at the last checkpoint when the services are restored at the end of the maintenance period. With the exception of runs from Timers that reach their end criteria during the downtime, a Timer run scheduled during the downtime will execute as soon as the service is restored. If multiple Timer runs are scheduled during the downtime, only one run will execute when the service resumes. We recommend that users check the state of their Timer runs after services have resumed. Flow runs that attempt to start a new step during the downtime will fail. We recommend that users check the state of their flow runs after services have resumed. Compute tasks submitted before the downtime will be available once services are restored. If this maintenance window causes a significant problem for you or those you support, please contact support@globus.org as soon as possible.
