OSG Hub Maintenance Nov 18, 2025 14:00-23:00 UTC
Update -
It has come to our attention that email notifications may have not been sent for the OSG Hub maintenance announcement yesterday (copied below):
We will be taking OSG Hub (hub.opensciencegrid.org) down for maintenance on November 18, 2025. During this time, the service will be intermittently unavailable, potentially causing failures in container artifact pulls or pushes.

OSPool ap20-21 Migration Dec 8, 2025 00:00 - Dec 15, 2025 00:00 UTC
The Open Science Pool (OSPool) is migrating Access Points ap20.uc.osg-htc.org and ap21.uc.osg-htc.org to new systems hosted at the University of Wisconsin–Madison in December 2025. Users on these Access Points (ap20 and ap21) will experience a downtime between December 8–15, 2025, during which job submissions and logins will be unavailable while data (/home and /ospool) is securely migrated. Once the migration is completed, migrated users will receive further instructions on how to login to the new APs and access their migrated data.
If your account is not on AP20–21 (for example, ap40.uw.osg-htc.org or ap1.facility.path-cc.io), no action is required. For full migration details, including the timeline, expected downtime, and post-transition steps, please visit the official migration guide: https://portal.osg-htc.org/documentation/support_and_training/ap20-21-migration-fall2025/
