Minor September 4, 2026 Microsoft - Exchange Online Errors 3h 34m
Started Sep 04, 2026, 12:27 PM UTC· resolved Sep 04, 2026, 04:01 PM UTC
- identified Sep 04, 2026, 12:27 PM UTC
We are monitoring reports of "Server busy" errors from Microsoft recipients. This issue has been identified by Microsoft (EX1467029), affecting users who may be attempting to send and receive email messages from external domains in Exchange Online. We will update when more information is available.
- identified Sep 04, 2026, 02:37 PM UTC
Microsoft has reported that mitigation for incident EX1467029 is being applied, and we are seeing a significant reduction in the number of “Server busy” responses from Microsoft. Some delivery attempts to Microsoft recipients are still being deferred, and messages affected earlier in the incident remain queued for retry. SocketLabs will continue retrying these messages automatically in accordance with normal delivery procedures. As Microsoft service continues to recover, we expect delayed messages to be delivered over time. We will continue monitoring delivery performance and Microsoft’s status updates.
- resolved Sep 04, 2026, 04:01 PM UTC
The Microsoft service issue associated with incident EX1467029 has been resolved, and delivery to Microsoft recipients has returned to normal. Messages delayed during the incident have been processed through our normal retry queues and the backlog has just about fully cleared. If you continue to experience delivery delays and issues to Microsoft recipients, please contact SocketLabs Support for further investigation.

We are currently investigating reports of delivery delays for certain customers.
- identified Jun 15, 2026, 02:51 AM UTC
We have identified networking issues affecting the SocketLabs US2-* region. Customers assigned to deliver messages via SocketLabs IP addresses in the 142.0.180.0/24 and 142.0.181.0/24 ranges may experience delays in outbound message delivery. Messages will remain queued and continue to be automatically retried for delivery as quickly as possible. Customers configured with IP addresses across multiple availability zones have been automatically failed over to their other available regions. Our engineering team is actively working with our upstream vendor to address the issue and we will provide another update as more information becomes available.
- identified Jun 15, 2026, 04:43 AM UTC
We continue to experience outbound delivery delays for customers assigned to the affected SocketLabs US2-* infrastructure. Our upstream vendor has confirmed a widespread carrier connectivity issue. Messages routed through the affected infrastructure remain queued and will continue to be automatically retried for delivery as quickly as possible. Customers configured with IP addresses across multiple availability zones remain failed over to their other available regions. Impacted customers may open a support ticket by emailing [email protected] to request a temporary reroute of their traffic while this issue remains ongoing. Our engineering team continues to work with our upstream vendor to address the issue, and we will provide another update as more information becomes available.
- monitoring Jun 15, 2026, 04:54 AM UTC
Our upstream vendor has confirmed that carrier connectivity has been restored for the affected infrastructure. We are continuing to monitor outbound delivery performance as queued messages are processed and delivery latency returns to normal. Customers may continue to see delays for some previously submitted messages while the remaining queue is retried and delivered. We will continue monitoring and will provide a final resolved update once message queues and delivery latency have fully normalized.
- resolved Jun 15, 2026, 05:16 AM UTC
All impacted message queues have cleared, and outbound delivery has been fully restored. Our upstream vendor previously confirmed that carrier connectivity was restored for the affected infrastructure. After continued monitoring, we have confirmed that message delivery latency has returned to normal. This incident is now resolved.

Minor March 4, 2026 Delayed Processing of Asynchronous Bounce Events 3h 30m
Started Mar 04, 2026, 03:30 PM UTC· resolved Mar 04, 2026, 07:00 PM UTC
- monitoring Mar 04, 2026, 03:30 PM UTC
We identified an issue affecting the processing of asynchronous bounce events within the SocketLabs platform. During this period, asynchronous bounce messages generated by receiving mail systems were delayed in acceptance and processing for some customers. Email delivery itself was not impacted. Messages continued to be accepted and transmitted normally, but asynchronous bounce-related events may have appeared delayed in customer dashboards, APIs, or downstream integrations. The underlying issue has been identified and corrective action has been implemented. Bounce events are now processing normally and the system is working through the remaining backlog created during the incident. We will continue to monitor the system to ensure processing remains stable.
