Nov <var data-var='date'>13</var>, <var data-var='time'>02:30</var> PST Resolved - On November 13th, Mailgun incorrectly rejected a subset of inbound emails with a 550 "recipient rejected" error. Senders received bounce notifications even though delivery should have succeeded. Affected timeframes: US region: 05:14 to 06:41 UTC and 14:55 to 15:48 UTC EU region: 14:55 to 15:48 UTC Based on our analysis, approximately 25% of US inbound traffic and 50% of EU inbound traffic had a chance to have been impacted during these windows. We're unable to provide exact counts due to gaps in our logging for rejected inbound mail, which we have since corrected.

Delayed Message Processing in US

Oct <var data-var='date'> 8</var>, <var data-var='time'>06:00</var> PDT Resolved - Between 12:55 UTC and 13:07 UTC, customers may have experienced email sending failures in the US region. A deployment of new code caused our sending pipeline to temporarily reject some email submissions with HTTP 500 or SMTP 451 errors (~ 2.5% of requests). Our team quickly identified the issue, rolled back the deployment, and restored normal service. Traffic was immediately shifted from the affected US region to the non impacted region to further mitigate customer impact while the rollback took place.
