Visiblio / Uptime Monitor
Know when an important page goes down.
Add the pages that must never break: the home page, a key category, a checkout step. Visiblio checks each one every 6 hours, keeps the answer and speed, and emails you when a page goes down and again when it is back.
How this works and what it can and cannot do
- Each page is opened every 6 hours (four checks a day) from Cloudflare's network. A page is "up" when it answers with a normal page (status below 400, redirects followed). A failed check is retried once straight away.
- It is called "down" after two failed checks in a row, so one slow moment does not send an alert. You get one email when it goes down and one when it is back, at the address you sign in with.
- The history keeps the latest 240 checks (about 60 days). Uptime is the share of those checks that were up.
- You can watch up to 10 pages. Only public pages can be watched. It does not log in, run scripts or look at the content: it checks that the page answers.
