We have observed a large increase in notifications from Microsoft Graph today and this has affected our infrastructure to result in higher latencies for new and updated messages for all grants across all providers. We have made changes to our infrastructure to better handle this increased notification traffic and we see that latencies have reduced. We are continuing to monitor this unusually high notification traffic and investigate the source of this higher notification traffic.

Mitigated - Sync latencies for new and updated messages in the US region have returned to normal operating levels following the infrastructure changes implemented earlier. We have mitigated the customer impact and are continuing to monitor performance while we investigate the unusually high notification traffic that contributed to the incident. The EU region remains unaffected.
- resolved Aug 11, 2026, 10:16 PM UTC
Sync latencies for new and updated messages in the US region have remained at normal operating levels, and our systems are stable. The changes implemented during the incident have mitigated the impact of the unusually high notification traffic. We will continue to monitor and address that traffic as part of our normal operations, but it is no longer affecting broader message synchronization performance. The EU region was not affected. This incident is now resolved. Thank you for your patience while we worked to address this issue.
