Some users may experience latency and buffering when attending Teams live events
Service Restored

More info: The problem intermittently impacted some live events and was specific to attendees. Impacted attendees saw a buffering spinning circle while attending live events and viewing previously recorded live events.
The service provider recommended users to switch to Teams town halls as they were not impacted.
All users that used Teams town halls saw Akamai as the Content Delivery Network (CDN) being used.
Final status: The service provider has identified that a portion of the CDN infrastructure that serves Live Events performed below acceptable thresholds, increasing request latency for some streams and resulted in attendee buffering. To remediate this issue, their content delivery partners restored the performance of the CDN infrastructure, which successfully resolved the impact, and they've verified resolution with the affected users.

Service Degradation

More info: The problem intermittently impacts some live events and is specific to attendees. Impacted attendees see a buffering spinning circle while attending live events and viewing previously recorded live events.
We recommend affected users to switch to Teams town halls as they are not impacted.

Current status: The service provider is investigating Teams live event service telemetry to identify what's causing the service degradation and increase in latency to help formulate a remediation plan. While they further investigate the underlying root cause, they recommend users temporarily switch to Teams town halls as they aren’t impacted. https://status.dal.ca/service.php?Service=43 2025-09-15 13:30:25 Resolved:

Final status: The service provider has identified that their previously-identified root cause, where impact appeared to be specific to users with policies disabling Copilot, may not have been the singular underlying source of impact. After further analysis, they determined that a portion of regional infrastructure leveraged to facilitate meeting creation entered an unhealthy state but has since recovered.

Service Degradation

More info: Affected users would be utilizing Hybrid Modern Authentication (HMA).

They'll provide a timeline for the completion of the deployment as one becomes available. https://status.dal.ca/service.php?Service=39 2025-08-22 10:47:45 TEAMS NOTICE
Some users may see a blank screen during meetings and calls from the Teams desktop version
Service Degradation

More info: This issue is limited to users who are on devices that leverage certain versions of Intel driver 32.0.101.69xx (including but not limited to, 32.0.101.6913, 32.0.101.6987, and 32.0.101.6989). Impacted users may see that Teams freezes for some time, and then it automatically recovers. For those that need immediate remediation, the service provider's telemetry indicates that version 32.0.101.6790 of the Intel driver reproduces this issue the least.
Affected users can use the Teams web app as a workaround until this issue is addressed.

Current status: The service provider is continuing to wait for confirmation to see if reverting to the last known healthy Teams desktop has resolved the isolated version driver issue. This evaluation will help determine if the reversion is a viable solution for mitigating impact across all affected users. Additionally, they've requested diagnostic logs from selected users to aid in identifying the root cause and developing a permanent fix. https://status.dal.ca/service.php?Service=39 2025-08-22 10:36:05 TEAMS NOTICE
Users may be unable to view the combined chat and channel view in the User Interface (UI)
Service Degradation

More info: The issue primarily affects the Teams desktop client. Users that have access to the Teams web client can use this to bypass the impact.
Additionally, users can temporarily work around the issue by clearing the cache in the desktop client.
Some users have reported that as a result of this impact, they can no longer access Teams channels due to the icon not being present in the left panel.

Current status: The service provider's log review has further identified that impact occurs when the code calls to the storage providing historical information and receives an invalid response. They're continuing to investigate why this invalid response is returned to determine potential remediation options. https://status.dal.ca/service.php?Service=39 2025-08-22 10:54:34 TEAMS NOTICE
