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.
