Deep Insights

See DNS, TLS, TTFB, and HTTP status to pinpoint the issue.

Plain English

Clear verdict, explanation, and next steps for every check.

Down for everyone, or just you?

When a website or API isn't responding, the first question is whether the problem is on your end or theirs. Every check runs from our servers—not your browser—so you get an unbiased, external result. The output breaks down DNS, TLS, timeout, and HTTP errors in plain English so you know exactly what went wrong.

Frequently asked questions

How do I check if a website or API is down?

Paste the URL and run the check. You'll see if it's down, plus a short explanation and suggested next steps.

Is the website down or is it just me?

If the website fails from our checker too, it is likely down for everyone. If it succeeds here, the issue may be local to your network or device.

What if the site is slow but not down?

Slow responses show up in the timing breakdown so you can spot latency, long TTFB, or upstream delays even when the server stays up.

Is OpenAI down right now?

Use the popular status section above to check if OpenAI is down. We test the OpenAI status page from our servers and report whether it responds normally.

Is Claude or Anthropic down?

Check the Anthropic card in the popular status section to see if Claude is down. The check runs externally so you get an unbiased result.

How do I check if AWS, GitHub, or Cloudflare is down?

We check the status pages of AWS, GitHub, Cloudflare, and Google Cloud. Click any card to run a live check, or use Check All to test them all at once.
