Incident
Temporary interruption in outbound email delivery
Resolved | Nov 16, 2023 | 14:29 GMT+01:00
Between Saturday November 11th ~00:00 CET and Monday November 13th ~10:00 AM CET no emails were sent out for Impact Stack action pages (confirmation-, thank-you- and email-to-target emails were affected). All emails that needed resending have been resent.
The incident was caused by an upgrade of our mail server on November 7th, which introduced a bug that caused part of the mail server to brake on November 11th because it was overloaded. The bug has been fixed and further steps have been taken to stabilise the mailing system to ensure the same problem doesn't happen again. We have also improved our monitoring systems to make sure that similar problems are detected and resolved within a shorter period of time.

Between Saturday 11.11. ~00:00 CET and Monday 13.11. ~10:00 AM CET no emails were sent out for Impact Stack action pages (so confirmation-, thank-you- and email-to-target emails were affected). We are in the process of investigating what caused this disruption.
No data has been lost. The bulk of these emails has already been resent today and we are currently working on a solution for the remaining ones.
