Investigating
We are currently experiencing delays with applying configuration and Kafka Integration changes to Clickhouse clusters via Terraform, the Cluster Management API and Management Console. During this time, making configuration changes to Clickhouse clusters may take longer than usual. Our team is actively working on resolving this problem and we apologise for any inconvenience caused.
Existing customer clusters are unaffected, and the Monitoring API and Prometheus API are operational.
Additional details will be provided as they become available. If you have an urgent matter, please reach out to us via the support portal (support.instaclustr.com) or email (support@instaclustr.com).
