Expert incident response for AWS

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 AWS is down. What should I do?

Check your account's AWS Health Dashboard for an event in your region first. If AWS reports nothing, find the first failing layer: a load balancer 502 or 504 points at your targets, a 503 usually means no registered targets, and Lambda failures show in its Errors and Throttles metrics. If the errors started with a deploy or configuration change, roll it back, then read the logs in CloudWatch.

1 Check AWS Health Your account's AWS Health Dashboard shows the service events that affect your own resources, by region.
2 Find the first failing layer Work from the edge in: CloudFront, the load balancer, then your targets or functions. An ALB 502 means a target sent a bad response or closed the connection, a 504 that it didn't answer in time.
3 Line it up with your last change Check recent deploys, CloudFormation or Terraform changes, and CloudTrail for configuration changes made around the time the errors started.
4 Roll back, then dig in Roll back the change if it lines up. Then read the CloudWatch Logs for the failing service and check limits like Lambda concurrency and database connections.

Guides for the errors you're seeing

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.

“@boristane - It is launch week for me and as I was testing Prod, started to notice things were not flowing like they did in Dev. Following @polylane for months & knowing I would try it when the time was right, I gave it a go. Issue Instantly ID. I was NOT disappointed. 🧑‍🍳💋”

Common questions

Is AWS down or is it my app?

Check the AWS Health Dashboard in your account. If it shows no event for your region and services, the errors are coming from your own resources: follow them from the load balancer inwards.

What does an AWS load balancer 502 mean?

The Application Load Balancer got an invalid response from a target, or the target closed the connection. Look at the target's logs: it's often crashing, restarting, or closing keep-alive connections early. More in our 502 guide.

Why is my Lambda function being throttled?

Lambda throttles when requests need more concurrency than is available, either your account's limit in that region or the function's reserved concurrency. The Throttles metric shows when it started.
