Incident Report for Linode

Postmortem

At ~ 13:22 UTC on Jun 23, 2025, a migration of a subset of servers between Linode core services was performed. During this migration, a process was incorrectly followed which resulted in the server set having a blank mapping table. Consequently, customers who were routed through this server set experienced resolution failures when attempting to access Linode-hosted domains. We identified this problematic server set and removed it from service at ~16:53 UTC on June 24, 2025 which restored resolution functionality. We will review our server upgrade process and identify/implement additional safeguards to prevent this issue going forward. We will also be introducing additional monitoring to detect this situation more quickly in the future.

This summary provides an overview of our current understanding of the incident given the information available. Our investigation is ongoing and any information herein is subject to change.
