1. IL-0167 A phased rollout of an LKE software release in Osaka stalled LKE-E cluster creation, version upgrades and control plane ACL changes

   Linode2026

   Symptoms

   From about 19:15 UTC on 12 March 2026, customers in the Osaka data center (JP-OSA) could not create Linode Kubernetes Engine for Enterprise (LKE-E) clusters. Cluster creation stalled indefinitely.

   Trigger

   A phased rollout of the LKE software release reached the Osaka data center.

   Root cause

   Faulty deployment

   Component

   Managed Kubernetes control plane and provider API

   Contributing factor

   –

   Detection

   The problem began at about 19:15 UTC, and the first status post, about five and a half hours later at 00:45 UTC on 13 March, said the team was investigating an emerging issue with deploying new LKE Enterprise clusters in Osaka.

   Remediation

   • deployed a software fix to mitigate the impact

   Action items

   • Investigate the root cause further and take preventive actions

   Lessons

   The problem followed a phased rollout of an LKE software release in the Osaka data center. There, cluster creation and administrative tasks stalled for more than six hours, and the first status post came about five and a half hours after the start.

2. IL-0161 A faulty earlier API update made new LKE cluster provisioning in Toronto time out for three days, leaving clusters with no node pools or the wrong number of nodes

   Linode2024

   Symptoms

   At about 14:05 UTC on 22 April 2024, Linode's team noticed that new LKE clusters were failing to provision in the Toronto data center.

   Trigger

   A previous update to the API did not work as intended and caused timeouts when new LKE clusters were provisioned.

   Component

   Detection

   Linode's team noticed new LKE clusters failing to provision in the Toronto data center at about 14:05 UTC on 22 April 2024.

   Remediation

   • disabled the affected section of Toronto infrastructure from provisioning new LKE clusters
   • implemented a fix for the faulty API update
   • put the disabled infrastructure back into use after the fix

   Lessons

   The fault was in an earlier API change, not in the infrastructure that showed it, but most failures concentrated on one backend resource in one data center. Taking that resource out of provisioning limited the impact while the root cause was found, which took three days.
