We are currently investigating reports of delayed or failed email deliveries to Apple-hosted domains. Messages to non-Apple domains are unaffected. We will provide updates as more information becomes available.

The issue was caused by an Apple iCloud Mail outage (https://www.apple.com/support/systemstatus/), which Apple has since marked as resolved. Bounce rates and delivery delays to Apple domains have returned to normal levels. We are currently reviewing our suppression lists to identify and remove any recipients that may have been incorrectly added during the incident.

Apple has implemented a fix and we are monitoring the results.

Delivery rates to Apple domains have returned to normal with no further elevated delays or bounces. We will perform any necessary post-incident cleanup of suppression lists to ensure no recipients were incorrectly suppressed during the outage. NOTE: As of Monday April 5th at 9PM EDT the cleanup has been completed. All recipient addresses to Apple or Apple Private Relay domains that were suppressed during Apple's incident window were removed.

This incident has been resolved.

We are currently seeing elevated temporary rejection rates for email delivered to Outlook.com, Hotmail, and other Microsoft-hosted addresses. Microsoft has acknowledged the issue and is actively investigating. This is a industry-wide issue and not isolated to any specific account. We will continue to monitor and update this page as we receive more information. Next update: When Microsoft posts a resolution or Bird observes delivery rates normalizing

Microsoft has confirmed that they made additional changes the night of Thursday, Feb 26th that should have remediated most IP rate limiting and rejection issues. If you are still seeing impacts, please reach out via your normal support channels and our team can investigate and escalate with Microsoft.

We are currently investing reported delays when sending emails towards Microsoft email domains

Impact is currently scoped to EU region only. Investigation ongoing; tickets raised to Microsoft to further investigation.

We continue to work with Microsoft on full mitigation. They are currently experiencing infrastructure issues that is causing them to incorrectly block legitimate traffic from multiple Bird IP ranges. Our sending infrastructure and email traffic are operating normally. All other mailbox providers are receiving mail without issue. Microsoft is aware of the issue and is actively investigating. We are in contact with their team and monitoring for resolution. We expect this to be resolved once Microsoft completes their fix. Messages will retry automatically - no action needed from you

Microsoft continues to investigate the issue. We are actively in contact with their team.

We continue to work with Microsoft on these delays. We are in active contact with their delivery team and working towards full resolution.

We have started to receive reports from Microsoft that they are implementing mitigations within their environment. We continue to monitor and coordinate with them for full resolution.

We continue to see some delays at Microsoft domains and are working with Microsoft to remediate. At this time, Microsoft is aware and continues to investigate.

We have seen stabilization, but are still seeing Microsoft delays in rare cases. Our team is mitigating with Microsoft as those occur. We are going to keep the status page in Monitoring state through the weekend as we continue to monitor for a full recovery at Microsoft.

We continue to see improvement with Microsoft delivery, though isolated cases of delays persist. Microsoft's mitigations are largely effective, but we're still working with their team to address edge cases as they arise. We will continue to maintain heightened monitoring through the week to ensure complete stabilization. No action is required from senders - any affected messages will continue to retry automatically.

We continue to receive reports of outages at Microsoft, as well as delayed mail sending to Microsoft and their related properties. If you are experiencing delays or IP blocks in sending to Microsoft related properties, please open a ticket with your Technical Account Manager or email support@bird.com (or your dedicated support channel if applicable). For detals around the Microsoft 365 please reference Microsoft's Status Page at: https://status.cloud.microsoft/m365

We continue to receive sporadic reports of outages at Microsoft, as well as delayed mail sending to Microsoft and their related properties. But have seen recovery for most senders.
