Nylas v3 Incident History

Webhook traffic has continued to function normally and all systems are operating correctly. Due to the time elapsed since the issue, we are no longer able to accept additional requests to replay the webhooks. Please reach out to Nylas Support for assistance retrieving items that may still be missing from this period.

We identified an issue that affected the delivery of a small percentage of message webhooks for some Nylas applications in the EU region. The issue primarily occurred between 06:00 and 11:00 UTC on July 24, 2026. Webhook delivery has recovered, and new webhooks are being sent successfully. Nylas applications in the US region were not affected. Customers who would like us to replay message webhooks should contact support@nylas.com as soon as possible and include their Nylas application IDs, when available. Please note that we cannot replay only the webhooks that were not successfully delivered. A replay will resend all message webhooks from the start of the incident through the time the replay is performed and will generate duplicates. Before requesting a replay, customers should ensure that their systems can safely identify and handle duplicate webhook events. We are continuing to investigate the underlying cause and closely monitor webhook delivery.

Webhook traffic has returned to normal and all systems are operating correctly. Due the time span elapsed since the issue, we are no longer able to accept any additional requests to replay the webhooks. Please reach out to Nylas Support for assistance retrieving items that may still be missing from this time.

The changes deployed have restored Notetaker meeting join performance for Zoom to normal operating levels, and our monitoring confirms that the issue is no longer affecting customers. We will continue to monitor performance and pursue further improvements as part of our normal operations. This incident is now resolved. Thank you for your patience while we worked to address this issue.

<b>Mitigated</b> - We have deployed changes that have materially improved meeting join success rates. We are continuing to monitor performance closely and are progressively expanding the mitigation while evaluating additional improvements. We will provide another update as this work progresses.

Our engineering teams continue to actively investigate the issue and are pursuing multiple remediation paths in parallel. The measures implemented so far have not resulted in a sustained improvement, and we remain focused on identifying an effective mitigation. We will provide another update as soon as we have meaningful progress to share.

We continue to work with our service providers and internal engineering teams to investigate the issue and evaluate potential mitigations. We will provide additional updates as our investigation progresses.

We are currently investigating degraded join rates for Notetaker on Zoom meetings (other meeting providers are not affected). We will share updates as we have more information.
