- identified · Oct 11, 2026, 05:51 PM UTC
We are investigating an increase in delayed (deferred) messages in both our US and EU regions, beginning at approximately 14:40 UTC on October 11. A subset of our internal DNS resolvers are intermittently failing to resolve recipient domains, causing some delivery attempts to be temporarily deferred. Affected messages are not being dropped or bounced. Retries are succeeding as they are routed to healthy resolvers, so impacted messages are being delivered with additional latency. Customers may observe an elevated number of delay events in webhooks, event logs, and reporting during this time. We have identified the cause as a DNSSEC validation issue on a portion of our resolver fleet related to a scheduled update of the internet's root DNS signing key, and are applying a fix. No action is required from customers. We will provide an update within 60 minutes or as soon as we have more information.

Some email deliveries are being delayed. The delays come and go, and queued messages are being delivered once each one clears. Our team is investigating the cause and working on a fix. We'll post an update here as soon as we know more. We apologize for the disruption.

We've made changes to address the intermittent delivery delays. Since then, email has been delivered without delay, including during peak sending periods that previously caused the slowdowns. We're watching closely to confirm the issue is fully resolved and will post an update here. Thank you for your patience.
