A Neon compute autosuspends when idle, so the first query after a pause pays a cold start

Neon scales a compute endpoint to zero after a period with no connections, five minutes by default on the free plan, and the next connection has to start it again. The first query then takes noticeably longer than the steady state, which appears as an occasional slow request rather than an error, and as a hard failure when the client's connect timeout is set aggressively low.
Paid plans can raise the suspend delay or disable autosuspend for an endpoint. On the application side, set a generous connection timeout and retry once on connect failure. Avoid health checks whose only purpose is keeping the compute awake, since that removes the saving the feature exists to provide. A pooled connection string does not prevent suspension: the pooler itself does not hold the compute open.
