Limited OSPool scheduling due to OSDF maintenance
Resolved - The OSPool is back to normal scheduling.
Feb 5, 16:26 UTC
Identified - The OSPool will be configured to only run a small number of jobs due to the upcoming OSDF maintenance (https://status.osg-htc.org/incidents/0qfv6rn07gpm). Users might see fewer jobs running, and longer queue times. Queued jobs will automatically start running once the maintenance has been completed.
Feb 5, 05:07 UTC
OSDF Central Services Maintenance
Completed - We've encountered some issues and have decided to postpone this maintenance. All services are operational.
Feb 5, 16:05 UTC
In progress - Scheduled maintenance is currently in progress. We will provide updates as necessary.
Feb 5, 15:30 UTC
Scheduled - We will be taking OSDF central services down for maintenance on February 5, 2026. During this time, all OSDF clients (e.g., HTCondor jobs, Pelican CLI, or PelicanFS using osdf://) will fail with timeouts to connect to the OSDF director.

Network issue affecting some OSG/OSPool services
Resolved - The network issue has been resolved.
Jan 30, 20:49 UTC
Investigating - Some secondary OSG/OSPool services are affected by a network issue. OSPool users might see condor_status commands hanging in some instances, and the secondary factory (gfactory-2.osg-htc.org) is not available.
Jan 30, 16:44 UTC
OSPool ap20-21 Migration
Completed - The scheduled maintenance has been completed.
Jan 30, 16:37 UTC
Update - 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.

Please refer to our transition page for more information: https://portal.osg-htc.org/documentation/support_and_training/ap20-21-migration-fall2025/
Dec 30, 21:39 UTC
Update - We are almost complete with the migration of user-facing services to UW for the OSPool.

All /home directories have been successfully transferred over to the /migration/ap2x/home/.tar.gz path.

Most of the /ospool data directories have also been transferred and are available under /migration/ap2x/data//.

If you cannot access the path, it means your directory is still in transit and should become available soon. Please refer to our transition page for more information: https://portal.osg-htc.org/documentation/support_and_training/ap20-21-migration-fall2025/
Dec 19, 23:10 UTC
Update - 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.
Dec 15, 22:20 UTC
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.
Dec 15, 17:55 UTC
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.
Dec 11, 16:02 UTC
In progress - Scheduled maintenance is currently in progress. We will provide updates as necessary.
Dec 8, 00:00 UTC
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. 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/

GRACC Accounting Outage
Resolved - GRACC was affected by the other associated central services outage, and it has now recovered.
Jan 27, 15:16 UTC
Investigating - The GRACC OSG Accounting database is failing to ingest records due to an exhaustion of disk space. Until we are able to expand the disk space, GRACC is unresponsive.
Jan 26, 21:45 UTC
Various central services outages
Resolved - Datacenter power has been steady over night and all services are operational.
Jan 27, 14:30 UTC
Monitoring - We have identified a power issue affecting multiple hosts in one of our datacenters and have taken measures to bring them back online. Affected services have recovered and we are continuing to monitor the situation.
Jan 26, 22:30 UTC
Investigating - Several central services are unresponsive due to filesystem issues at UW.
