Is TPx Communications Down?

TPx provided Office 365 services are performing as expected. Out of an abundance of caution Microsoft is continuing to monitor their systems. They continue to observe sustained service recovery across the previously affected environments. Due to the severity of impact this incident caused, TPx and Microsoft will continue monitoring to ensure no additional mitigative actions are required. Microsoft will continue to also monitor the backlog of email messages accrued during this event to ensure all process successfully before considering the issue resolved. If you believe your service is impacted, please open a Technical Support case in the TPx Customer Portal at portal.tpx.com --- [2026-11-13T07:24:05.848-08:00] (monitoring) Microsoft recovery efforts are ongoing across their impacted infrastructure. TPx is seeing early signs of stabilization and Office 365 services appear to be functioning normally. Microsoft is still monitoring service capacity, as capacity has not yet returned to normal levels and health remains variable as traffic is carefully reintroduced. Their primary focus is on service stability and a controlled recovery. They have extended the email timeout window to 48 hours to help protect delayed messages while service recovery continues. Microsoft and TPx will continue to treat this event with urgency until full mitigation and recovery is completed. If you believe your service is impacted, please open a Technical Support case in the TPx Customer Portal at portal.tpx.com --- [2026-11-13T00:23:37.865-08:00] (monitoring) Microsoft seeing positive results for server stability after applying an upstream authentication/routing configuration component patch to a portion of their infrastructure. They will continue to monitor its progress and working to expand it to servers supporting active regions coming online. If you believe your service is impacted, please open a Technical Support case in the TPx Customer Portal at portal.tpx.com --- [2026-11-12T22:01:20.284-08:00] (monitoring) Microsoft continues to pursue multiple workstreams to pinpoint the underlying cause of the traffic influx and advance the recoverability of the backend servers. They are tracking the results of this approach to verify the servers are showing the anticipated recovery and performance intended. They are seeing intermittent recovery of services, however appropriate stability and capacity is still being under recovery. As of now, they are not aware of any malicious activity that is causing this incident. They will continue to treat this incident with urgency and priority until full resolution. Once mitigated, they will provide full details of the root cause, defense-in-depth repair items, and more within a Post-Incident Report. If you believe your service is impacted, please open a Technical Support case in the TPx Customer Portal at portal.tpx.com --- [2026-11-12T20:39:32.470-08:00] (identified) Microsoft is continuing efforts to improve server stability and improve traffic flow. This includes adjusting traffic protocols, redistributing traffic, and applying strategic traffic blocking measures. They are observing partial recovery across regions in which they applied these adjustments; however, these actions aren't resulting in sustained recovery, so they are reviewing what additional actions they can take to improve overall infrastructure stability. If you believe your service is impacted, please open a Technical Support case in the TPx Customer Portal at portal.tpx.com --- [2026-11-12T19:21:37.609-08:00] (identified) Microsoft has monitored the status of the changes applied to improve serviceability and confirmed that the change is not taking as expected. They are identifying alternate workstreams that can be applied to increase capacity in the face of sustained traffic management imbalances. If you believe your service is impacted, please open a Technical Support case in the TPx Customer Portal at portal.tpx.com --- [2026-11-12T18:12:19.605-08:00] (identified) Microsoft is seeing positive results with our efforts to restart affected infrastructure. They are actively monitoring the performance of these to verify stability which will support improved availability. Remediation actions will be expanded as they confirm stability with the changes applied. If you believe your service is impacted, please open a Technical Support case in the TPx Customer Portal at portal.tpx.com --- [2026-11-12T15:30:35.700-08:00] (identified) Microsoft has begun returning a portion of the affected servers to service, and they are remaining stable so far. They have also shifted traffic and connections to alternative pathways wherever possible and have observed limited recovery in some regions. Microsoft has streamlined their recovery process to expedite returning the remaining affected servers to service. To further support recovery, they are implementing protective traffic management measures in a specific location to reduce load on the affected infrastructure, and expanding these measures to additional locations if they observe positive results. As capacity is restored, users may experience a gradual recovery as their clients reconnect to the service. If you believe your service is impacted, please open a Technical Support case in the TPx Customer Portal at portal.tpx.com --- [2026-11-12T15:07:12.343-08:00] (identified) Microsoft is continuing to pursue all available pathways to restore service, as their actions taken thus far have not provided the anticipated relief. Their investigation has found that a core process on the affected servers is becoming overwhelmed, which causes the servers to stop responding and contributes to the capacity loss. To validate a potential recovery approach, they are fully isolating a portion of their service infrastructure, restarting the affected components, and gradually reintroducing traffic to confirm our services remain stable before applying this approach more broadly. If you believe your service is impacted, please open a Technical Support case in the TPx Customer Portal at portal.tpx.com --- [2026-11-12T14:23:34.741-08:00] (identified) Microsoft is continuing to work through restarting and validating the affected servers to safely return them to service, and they are exploring opportunities to expedite this process. In parallel, they are assessing whether reverting the small number of recent configuration updates they identified could help accelerate recovery. If you believe your service is impacted, please open a Technical Support case in the TPx Customer Portal at portal.tpx.com --- [2026-11-12T11:38:31.607-08:00] (identified) Current status: Microsoft is aggressively pursuing all pathways to reduce impact. As a precaution, they've paused all deployments and configuration changes while reviewing recent changes for any correlation to this event. They've determined that the elevated load isn't driven by an overall increase in traffic, but by a large number of servers being unexpectedly unavailable, which is shifting load onto the remaining infrastructure. They are investigating what's causing these servers to become unavailable while they work to safely return them to service.
