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 probe to avoid false alarms, and alerts you within seconds via email, Slack and more.
Don’t check it once — watch it 24/7
A single test can’t catch a 3am outage. CompleteStatus runs this exact check around the clock and alerts you the moment something changes — before your users (or attackers) notice.

Uptime is table stakes. We watch the rest — security headers, email authentication, certs and DNS, with the fix attached.
