Blackboard Status

Resolved: This incident has been resolved.

Monitoring: Real time processing queues have returned to normal levels while the team continues to monitor.

Monitoring: The Ally development team has scaled up resources based on demand and will continue to monitor progress.

Identified: We are experiencing another spike in activity which has caused intermittent delays in the processing of content added to the LMS for institutions in the US. Real time processing delays of approximately 1.5 hours for new content items may be seen during this time.

Note that all other Ally features (alternative formats, instructor feedback and institutional report) for previously processed content items should still be working as expected.

Monitoring: We are aware that some of the broken links were not resolved last week after deploying the fix. We are currently investigating the impact in order to determine next steps.

Monitoring: The broken links fix will be deployed with the Thursday, March 19, 4000.10.0 maintenance release. While this is expected to resolve the majority of broken links there is one unique scenario that cannot be corrected. When an embedded file has the same filename and extension as another embedded file in the same document, we are unable to determine which backup file it originally corresponded to, and therefore the link cannot be corrected. After the release, organizations will be provided with a list of unresolved file references (if applicable).

Monitoring: A fix has been implemented for this issue and it will be deployed with the Blackboard SaaS 4000.10 maintenance release to production this week on March 19th.

Identified: The fix is in the final testing phase. We will provide timing for deployment of the fix early next week.

Identified: Testing of the fixes for the broken links is underway. To ensure a successful fix, we have decided to conduct additional rounds of testing, therefore the broken link fix will not be included in this week’s Production release. We will confirm and share a new timeline for release in the next few days. Thank you for your continued patience.

Identified: Contingent on successful testing, the fix to restore the broken file references is expected to be released with the 4000.10 release to Production environments scheduled for Thursday, March 5th.

Investigating: Development of the solution to resolve this issue is still underway and preliminary testing has started. We are tentatively targeting a release of the fix by the end of next week. Additional updates will be provided next week.

Investigating: The team is currently working on the solution for this issue and hope to have an estimate of the timeline for delivery of the fixes by the end of this week.

Investigating: We are continuing to work through identifying the full set of impacted courses and content items and determining next steps for restoration. Another update will be provided early next week.

Investigating: The team continues to make progress on identifying the full set of impacted courses and content items. Once complete we will be able to begin restoration. A timeline for affected file restorations will be shared once it's available.

Investigating: We have confirmed the root cause related to the recent 4000.8 release and have already implemented a fix to prevent any new link corruption from occurring. Our current focus is remediation of impacted content. The team is taking a structured recovery approach that includes:

• Preserving all relevant system data to ensure no additional information is lost during cleanup
• Identifying the specific courses and content items affected
• Creating secure backups of impacted content records
• Comparing current content with archived versions to accurately restore file references where we have full confidence in the correction
• Flagging any items requiring additional validation for follow-up review

Several of these remediation steps are being executed in parallel to accelerate resolution. We will provide further updates as restoration progresses and will share additional guidance if client action becomes necessary. At this time, no action is required from clients.

Investigating: The team understands the issue and problems caused. They are investigating the path forward to provide a fix to clean up any corrupted links. Additional information will be provided as it becomes available.

Investigating: With the release of Blackboard SaaS 4000.8 to production last week, there was a change that inadvertently may have caused some links to become corrupted. In a specific scenario where a document included PDF attachments from more than one course, an attachment from a different course may no longer be referenced correctly. In some cases, the document may display an incorrect PDF or an attachment may not open as expected. Note: This can happen with any file types that are cross-referenced too (not just PDFs)
