We are investigating. https://status.thalassa.cloud/incident/988311 Fri, 14 Aug 2026 09:06:00 -0000 https://status.thalassa.cloud/incident/988311#01d374dd2719bc1fe732938a25a273893402bf010ea583117bde2c1691925f52 Incident On 31 July 2026, we deployed an updated Kubernetes node specification containing additional virtualization hardening measures. The specification change was unintentionally picked up by our automation as requiring node replacement, resulting in a platform-wide rollout. Safeguards were already in place to restrict these actions to scheduled cluster maintenance windows. Despite these safeguards, hundreds of Kubernetes nodes started being replaced simultaneously. Two issues occurred during the rollout that further delayed node replacements and caused temporary disruption for a small number of clusters. ## Root Cause ### Node Replacement We determine whether nodes require replacement by calculating a hash from relevant parts of the node pool specification. Safeguards and tests are in place to prevent configuration changes from unintentionally changing this hash. The new hardening setting defaults to `false` and was intentionally excluded from this calculation until enabled. The Kubernetes deployment layer normally enables the setting during the next scheduled maintenance window. However, deploying the updated specification also changed the instance type specification referenced by existing node pools. This caused the node pools to reconcile immediately and resulted in the new hardening configuration being applied outside the expected maintenance flow, triggering node replacements across the platform. ### Slow Node Provisioning Hundreds of nodes were provisioned and decommissioned within a short period. Some node drains were blocked by Pod Disruption Budgets (PDBs) or workloads taking longer to terminate. These drain operations occupied our node lifecycle controllers for up to 10 minutes per attempt, reducing the capacity available to provision replacement nodes. In some cases, new nodes took up to one hour to join a cluster. ## Remediation * Improved the node drain timeout and retry logic to prevent individual drain operations from blocking overall node lifecycle processing. * Added additional validation and safeguards to prevent unintended node replacements outside scheduled cluster maintenance windows. * Improved Kubernetes cluster and node testing in our staging environments to verify that nodes are not replaced outside their maintenance windows, in addition to the existing specification hash tests. https://status.thalassa.cloud/incident/1010811 Thu, 13 Aug 2026 13:23:00 -0000 https://status.thalassa.cloud/incident/1010811#959cdf2b388446a1864fddd1b6c378acd24f0af300151430d053e274a3b70afa Incident All systems are operating at normal levels again. https://status.thalassa.cloud/incident/1010811 Thu, 13 Aug 2026 13:16:00 -0000 https://status.thalassa.cloud/incident/1010811#b5b4a092f1ac8c8c89ed95a8e35d02eae7f62b60ed972d332460b34d140aaa3d Incident We are currently experiencing a large influx of operations on our volume provisioning system.
