# Expert incident response for Google Cloud

> Our founding team picks up your incident, and Polylane's agents dig through your logs, metrics, traces and code with them.

- **Real engineers who've carried the pager.** The team has been on-call at Cloudflare, Webflow, Groq, Twilio, and Robinhood. They've been where you are right now.
- **Multi-cloud incident response.** Polylane investigates incidents across AWS, Cloudflare, Vercel, Kubernetes and the rest of your stack, from the edge to the database.
- **Unified context & investigation.** Logs, metrics, traces, deploys and code in one context graph. Connect in minutes, not weeks.
- **Least-privilege access.** New cloud accounts connect read-only, with scoped credentials. Nothing in production changes unless you allow it.

## My app on Google Cloud is down. What should I do?

Check the [Google Cloud status dashboard](https://status.cloud.google.com/) and Personalized Service Health in your console first. If Google reports nothing, find the failing service: Cloud Run returns 503s when instances crash or never start, and a load balancer 502 usually means unhealthy backends. If the errors started with a deploy, send traffic back to the previous Cloud Run revision with `gcloud run services update-traffic`, then read the logs in Cloud Logging.

1. **Check Google Cloud's status.** The [status dashboard](https://status.cloud.google.com/) lists incidents by product and location, and Personalized Service Health in the console shows the ones affecting your projects.
2. **Find the failing service.** Cloud Run 503s mean instances are crashing or not starting: a container that doesn't listen on `$PORT` never becomes ready. A load balancer 502 usually means its backends are failing health checks.
3. **Line it up with your last change.** Compare when the errors started with your latest Cloud Run revision, GKE rollout or Cloud Build deploy. `gcloud run revisions list` shows recent revisions.
4. **Roll back, then dig in.** `gcloud run services update-traffic SERVICE --to-revisions=REVISION=100` sends all traffic back to a known-good revision. Then filter Cloud Logging by severity and resource to find the first error.

## How we resolve active incidents

1. **Rapid onboarding.** A Polylane engineer reaches out, connects Polylane to your clouds, code and telemetry, and confirms what's affected.
2. **Investigation & mitigation.** Polylane's agents investigate across logs, metrics, traces and recent changes, and an engineer works with you on the right mitigation.
3. **Remediation, validation & monitoring.** The fix lands in your repo for your team to review. Polylane checks that things are back to normal and keeps watching every deploy after it.

## Why teams choose Polylane

- **Every cloud in one graph.** AWS, Cloudflare, Vercel, Kubernetes and more, mapped into one context graph with your code.
- **Connected in minutes.** Connect with OAuth or the CLI. No agents to install, no code changes.
- **Real engineers on the other end.** Your report goes straight to the people who build Polylane.
- **Evidence for every claim.** Every finding links to the log line, metric or deploy behind it.
- **You stay in control.** Read-only by default. Nothing writes to production unless you allow it, and you can switch it off at any time.
- **Works with your coding agents.** Claude Code, Cursor and other agents reach Polylane over MCP, so they can dig in with you.

## Common questions

- **Is Google Cloud down or is it my app?** Check the [status dashboard](https://status.cloud.google.com/) and Personalized Service Health. If neither shows an incident for your products and region, the errors are coming from your own services.
- **Why is Cloud Run returning 503 errors?** Usually the container crashes at startup, doesn't listen on the port in `$PORT`, or runs out of memory. The revision's logs in Cloud Logging show which.
- **How do I roll back on Cloud Run?** Route traffic back to the previous revision, from the service's Revisions tab or with `gcloud run services update-traffic`. Old revisions stay deployed, so no rebuild is needed.
- **Who will help me with a Google Cloud incident?** Our founding team, engineers who have carried the pager for production systems at scale, working with Polylane's agents across your Google Cloud projects, code and telemetry.

## Report an incident

Use the form at https://polylane.com/incident-hotline/gcp/. If the form fails, email support@polylane.com.

For agents: there is no public API for this form, because it is protected by Cloudflare Turnstile. Open the page in a browser and fill it in for the user; coding agents with a browser tool can do this. Confirm the details with the user before you submit. The fields: Name, Company name, Work email, How bad is it? (Production is down / Degraded for some users / Something's wrong, we can't find it), Are you on Polylane? (Already on Polylane / Not yet) and what's broken, plus optionally a phone number, when it started (Just now / In the last few hours / Days ago).
