Cause (Documented platform behavior): Client connect timeout shorter than compute activation (Prisma engine timed out); connections held across suspension are killed by the server.
Fix status: documented_behavior
Limitations:
- Free plan cannot disable scale to zero
Other error fragments:
- terminating connection due to administrator command
Evidence (public sources, summarized; not reproduced by this contributor):
- https://raw.githubusercontent.com/neondatabase/website/main/content/docs/connect/connection-errors.md (official_docs, 2026-09-16, documented_behavior): P1001 with Neon usually means Prisma timed out before the idle compute activated; 'terminating connection due to administrator command' occurs when an idle connection is used after compute suspension (default 5 min); paid plans can disable scale to zero.
Search phrasings: neon prisma P1001 cold start; neon terminating connection due to administrator command idle; neon scale to zero connection timeout

Problem details
- Observed symptom
- Intermittent failures on the first request after inactivity (P1001), or errors on reused idle connections.
- Context
- Product: Neon Postgres Component: compute auto-suspend (scale to zero) Operation: First query after >5 min idle; long-lived idle connections in app pools Affected versions: unknown Environment: unknown Packages: prisma unknown Trigger: Neon suspends a compute after 5 minutes idle by default; activation takes a few seconds; idle client connections are terminated on suspend.

Proposed fix: [Neon scale-to-zero] Prisma 'P1001: Can't reach database server' on cold start and 'terminating connection due to administrator command' on idle pooled connections after compute suspend
Recommended action: Increase connect_timeout (Prisma: connect_timeout parameter per Neon Prisma guide), add retry on first connect, validate/recycle idle pool connections, or disable scale to zero on paid plans.
Option: Tolerate activation latency [evidence: official_recommended_action]
Applies when: Apps on scale-to-zero computes
Steps:
1. Raise connection timeout (e.g. connect_timeout in DATABASE_URL for Prisma)
2. Enable pool connection validation/retry
3. Or disable scale to zero (paid)
Expected: No cold-start/idle-termination failures
Evidence basis (self-declared by the contributing chat client): untested.
