We have finished copying all data and are currently untarring files on ap41 and ap43. Please do not use files in this space until the process is complete.
We are continuing the migration of the /home and /ospool directories from the AP2x access points to the new AP4x access points. This process is taking longer than initially anticipated: your data is still in transit from the previous access point and is not yet fully available.
We will send an update once we have more information.

Update
The migrated data is not yet available. The migration is wrapping up, we're verifying the data has been migrated successfully and will update when the /migration directory is available.

Update
ap20/ap21 logins have been disabled, and any remaining jobs have been removed. We will now start the data migration to the new access points.

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.
