Pantheon Is Green, But Your Deploy Still Needs a Gate

import TOCInline from '@theme/TOCInline';

Pantheon reporting "All Systems Operational" is a good signal, but it is not a deploy approval by itself. I treat platform status as one input in a release gate that also checks app health, migration safety, and rollback readiness.

TL;DR — 30 second version

  • A green vendor status page is necessary for timing, not sufficient for safety
  • Most post-deploy incidents are local to your code, data shape, or traffic pattern
  • Build a compact release gate with explicit pass/fail criteria
  • If you cannot roll back confidently, you are not ready to deploy

Why I Built It

I kept seeing the same failure mode: teams read a green vendor status page, ship quickly, then spend hours debugging issues that were never platform-level. A healthy provider does not guarantee your config import, schema change, or cache invalidation path is safe.

The real problem is decision quality at deploy time. I needed a repeatable way to separate platform risk from application risk before pressing the button.

The Release Gate

I now use a compact release gate with explicit pass/fail criteria. Vendor status is only one branch.

Pre-Deploy Script Example

```bash title="Terminal — release gate check" showLineNumbers

!/bin/bash

Lightweight release gate — run before every production deploy

echo "=== Release Gate Check ==="

1. Platform status

echo "Checking Pantheon status..."
curl -s https://status.pantheon.io/api/v2/status.json | jq '.status.indicator'

2. Staging smoke test

echo "Running smoke tests on staging..."
drush @staging status-report --severity=2

3. Config validation

echo "Validating config import..."
drush @staging config:import --dry-run

4. Rollback path

echo "Confirming rollback lockfile exists..."
test -f composer.lock.rollback && echo "PASS" || echo "FAIL — no rollback lockfile"

<details>
<summary>My minimum release gate before production deploys</summary>

- Platform status is operational.
- Smoke checks pass on staging with production-like data shape.
- Migration/config changes are reversible or explicitly one-way with a fallback plan.
- Error budget is healthy (no unresolved high-severity incidents in the app).
- Rollback owner and command path are confirmed before deploy.

</details>

### Caveats and Gotchas

- Status pages can lag short incidents or edge-region issues.
- "Operational" does not cover every third-party API your app depends on.
- If your deploy includes risky data transforms, platform health is almost irrelevant to the main risk.

## The Code

No separate repo, because this is an operational release policy pattern rather than a standalone build artifact.

## What I Learned

- Vendor status is worth checking when scheduling deploy windows, not for approving deploy safety.
- Avoid using one binary signal for release decisions in production.
- A small release gate beats heroic incident response every time.
- If you cannot roll back confidently, you are not ready to deploy even when the platform is green.

## Signal Summary

| Topic | Signal | Action | Priority |
|---|---|---|---|
| Platform Status | Necessary but not sufficient | Use for timing, not approval | High |
| App Health Checks | Local risks are the real threat | Run smoke tests on staging | High |
| Rollback Path | Must be tested before deploy | Confirm owner + command path | Critical |
| Config Validation | Bad imports cause outages | Dry-run config import in staging | High |

## Why this matters for Drupal and WordPress

Pantheon hosts both Drupal and WordPress sites, so this release gate pattern applies to both CMS platforms — `drush config:import --dry-run` for Drupal and `wp core verify-checksums` for WordPress serve the same pre-deploy validation role. WordPress teams on Pantheon often skip config validation because WordPress lacks a native config-import system, but checking database migrations, plugin compatibility, and cache invalidation paths is equally critical. For agencies deploying both Drupal and WordPress on Pantheon, standardizing a single release gate script that branches by CMS type eliminates the "we forgot to check the WordPress site" failure mode.
