ClickHouse Cloud is the managed version of the ClickHouse columnar database, used for analytics over very large datasets. Ingestion and query serving scale separately, so an incident often means inserts backing up while dashboards continue to query slightly stale data.

What to do if ClickHouse Cloud is down for just you

  • Check your connection limit and pool settings first, since exhausting connections looks exactly like the database being down.
  • Retry with a longer timeout, because a serverless or scale-to-zero instance may simply be waking up.
  • Confirm your credentials and IP allowlist have not changed, as an auth or firewall denial reads as a failed query.
  • Query from another network or client to establish whether the cluster or your route to it is the problem.
