Is the site up, and how often is it down?
Each time we check your site we get back a healthy page, a redirect, an error, or nothing at all. We label that result, and that label shows up everywhere. Click a status to see exactly what your visitors would experience.
The six statuses, and what your visitors see
Every check ends with one of these labels. The screen below shows the moment a real visitor would be having on your site for each one.
Site is up
Your site responded with a normal page inside the timeout. Visitors load the page just fine.
Site is down
Your site returned a server error or refused the connection. Visitors are seeing an error right now.
Timed out
The site took longer than 10 seconds to respond. We try once more before alerting, since one slow check is often a blip.
SSL issue
Your certificate is expired, untrusted, or the chain is broken. Browsers show a scary red warning before letting visitors in.
DNS issue
We could not turn your domain into an IP address. Often a misconfigured DNS record or an expired domain.
Rate limited
Your server, a CDN, or a WAF is throttling requests. Common during traffic spikes or when bot protection is too aggressive.
What an uptime percentage really costs
If you ran 100 checks and 99 came back UP, your uptime is 99%. We show this over the last 48 hours on every site. It sounds great, but 99% works out at nearly 15 minutes of downtime every day. That is a checkout that fails for 15 minutes of shoppers. Most production sites aim for 99.9% or better.
Our demo status page tracks major websites with these exact labels, live. When a status goes red there, this page tells you what it means. Slow-but-up sites are covered in the performance guide.
