Ad serving impacted for Applist targeted Campaigns

Incident Report for Kayzen

Resolved

We experienced a technical issue between 06:45 UTC and 07:05 UTC, 9th Feb 2026 that have affected campaigns where:

1. A new Applist was created and attached to the campaign, or an existing Applist already attached was modified.
2. A Placement ID is manually blacklisted via the campaign detail page.

These campaigns stopped bidding and ad serving was disrupted. Campaigns without Applists, or those where no changes were made to Applists, were unaffected.
We apologise for the inconvenience. Please reach out if you have any questions.
