Scheduled

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.
