When PlanetScale Goes Down: A Survival Guide for Your Team

It's mid-afternoon and your error tracker lights up. Every request that touches the database is timing out. The app's static pages load fine, so at first glance the site looks up — but logins fail, the dashboard spins, and orders won't save. Somewhere between your app and PlanetScale, the connection broke, and a 'mostly up' site is quietly failing every user who tries to do anything real.

What Happens on Your Team

The Backend Engineer

Sees connection timeouts in the logs. Is it the connection pool? A bad deploy? A PlanetScale incident? Checks the status page — still green. Starts bisecting recent changes while the clock runs, unsure whether the problem is their code or the platform.

The real cost: Database failures are ambiguous. Without a monitor that isolates the data path, the engineer burns time deciding whether it's their app, their config, or the provider — before they can even start fixing it.

What they should have had: A monitor on a health endpoint that runs an actual query against PlanetScale. When that endpoint fails while static pages stay up, the alert points straight at the data layer — no bisecting required.

The Product Owner

Gets a message that 'the site is slow.' Loads the homepage — it's fine. Loads the dashboard — it hangs. Can't tell stakeholders whether it's a minor blip or a full outage because the symptoms are inconsistent across pages.

The real cost: When only data-backed pages fail, the outage is invisible to surface-level checks. The product owner has no clear signal to act on, so the response is delayed and the messaging to users is vague.

What they should have had: A monitor on a database-dependent route plus a status page. One glance shows that data operations are down even though static content is up — turning a confusing situation into a clear status to communicate.

The On-Call Developer

Wakes up to scattered user reports overnight. By the time they log in, the connection issue has been failing intermittently for two hours. There's no record of when it started, so root-causing means guessing at a timeline.

The real cost: Intermittent database issues that aren't recorded leave no timeline. Without check history, the on-call dev can't correlate the failure with a deploy, a traffic spike, or a provider incident.

What they should have had: Continuous monitoring with recorded check history. The on-call dev opens the timeline, sees exactly when queries started failing, and correlates it with the deploy that happened minutes earlier.

Why Monitor PlanetScale?

Your database is the floor everything else stands on. If your app can't reach PlanetScale, every page that touches data fails — logins, dashboards, checkouts. You can't ping PlanetScale's internal servers, but you can monitor the app endpoints that depend on the database, so you find out the moment queries start failing instead of when users do.

What You Should Actually Do

1Monitor an app health endpoint that runs a real database query — not just a static route, so you actually exercise the PlanetScale connection
2Monitor a user-facing path that reads from the database — so you catch failures the way users experience them
3Set a slow-response threshold — database degradation often shows as creeping latency before a full failure
4Keep alerts on a channel independent of your app — so an outage doesn't suppress the notification
5Bookmark PlanetScale's status page for platform-wide incidents, but rely on your own monitors for connection and query issues

PlanetScale's Official Status Page

PlanetScale publishes real-time status at www.planetscalestatus.com. Monitoristic doesn't replace this — it complements it. The official page tells you when PlanetScale reports an issue. Your own monitor tells you when your connection is affected, often before the status page updates. You also get push alerts instead of checking a webpage manually.

You can't monitor PlanetScale's servers, but you can monitor the thing that matters: whether your app can actually run queries. The most dangerous database failures are partial — static pages load while every data operation quietly fails — making the site look up when it's broken for real users. A health endpoint that runs a real query, watched continuously, closes the gap between 'queries are failing' and 'you know queries are failing.'

Frequently Asked Questions

Can I monitor my PlanetScale database directly? +

Not the servers themselves — PlanetScale is fully managed. Instead, monitor an app health endpoint that runs a real query against the database. If that endpoint fails while static pages stay up, you know the data layer is the problem.

How do I tell a PlanetScale issue from an app bug? +

Monitor both a static route and a database-dependent route. If the static route is up but the query-backed route fails, the problem is in the data path — either your connection config or a PlanetScale incident. Cross-check with their status page.

What check interval should I use for a database-backed endpoint? +

For production apps, 1–2 minute checks catch connection failures fast. Add a slow-response threshold so you're warned about creeping query latency before it becomes a full outage. Monitoristic offers 5 min (Lite), 2 min (Pro), and 1 min (Business).

How is this different from PlanetScale's status page? +

PlanetScale's status page reports platform-wide incidents. It won't tell you that your specific connection pool is exhausted, your credentials expired, or your app can't reach the database. Only monitoring your own query-backed endpoint catches those app-specific failures.
