Website Uptime Test

Is your website down right now? Check it from our server — status code, latency and TTFB.

“Is it down, or is it just me?”

This test requests your site from our server, not your browser — so it cuts through local DNS, VPN and ISP issues. If we report it down too, the problem is server-side. If we see it up but you can’t reach it, look closer to home.

HTTP status

2xx/3xx means reachable; 5xx means the server is erroring; nothing means it’s unreachable.

Latency

Total round-trip time — high values hurt user experience and SEO.

TTFB

Time to first byte isolates server/backend slowness from transfer size.

Frequently asked questions

This test requests your site from our server, not your browser or network. If it reports the site as down here too, the problem is on the site’s side; if we see it up but you can’t reach it, the issue is likely your local network, DNS or ISP.

TTFB is the time from sending the request to receiving the first byte of the response. It reflects DNS, connection, TLS and server processing time — a high TTFB usually points to a slow backend.

Yes. This one-off test is a snapshot; CompleteStatus checks your site around the clock, confirms outages with a second consecutive check to avoid false alarms, and alerts you within seconds via email, Slack and more.
