Confirmed outage: 2 of 3 probes agree

Failure type: network. Alert sent by email and in the app.

AI in this tool

AI explains each outage in plain language, including the failure type and what to check first.

What you can do

  • Get default checks automatically after adding a site.
  • Choose critical pages, such as a services or contact page. These are page loads only, with no form submitting.
  • Get email and in-app alerts, with a recovery notice.
  • Set quiet hours and maintenance windows.
  • See what failed, from where, and when.

How an outage gets confirmed

  1. Take turns

    Each minute, one of 3 probes checks the site.

  2. Double-check

    If it fails, the other 2 probes check right away.

  3. Agree

    If at least 2 of 3 agree, it is a confirmed outage and you get an alert.

  4. Explain

    The alert names the kind of failure: DNS, SSL, network, server, application or content.

What gets checked, and how often

What is an AI website uptime monitor?

An AI website uptime monitor checks that a site loads, all day, every day, and explains each confirmed outage in plain language. Plain code runs the checks and confirms every outage from several locations. AI then tells you what failed and what to check first.

It is built for SEO agencies, in-house teams and developers who are tired of hearing about an outage from the client. Adding a site sets up default checks automatically, and you pick the critical pages, such as a services or contact page. Outages land in the same loop as your SEO problems, so nothing gets tracked in a separate app.

Why does downtime matter for SEO?

Downtime matters for SEO because search engines have to reach a page to crawl it, and repeated server errors tell them to slow down.

A short outage is rarely a lasting problem, since crawlers expect the odd failure and come back. The risk grows when 5xx replies repeat or last a long time. Crawling slows, and URLs that stay unreachable can eventually drop out of the index.

Visitors feel it first. Anyone who lands on an error page from a search result or a paid campaign leaves, whatever search engines do later. The real cost of an outage is the time between the failure and the moment someone acts on it, and that gap is exactly what this monitor closes.

What should a website uptime monitor check besides a 200 OK?

A website uptime monitor should also check DNS, the SSL certificate and the page content, because a site can fail at each of those layers while the others look healthy.

A DNS failure makes a site unreachable even when its server is fine. An expired certificate puts a browser warning in front of a working page. A 200 OK can still carry a blank page, an error message or a maintenance screen, which is why content gets checked with each page load.

Here, page loads run every minute, DNS every 5 minutes and the SSL certificate every 6 hours. The monitor also flags a new 4xx on a URL that used to work, redirect loops, unexpected DNS changes and pages much slower than the site's normal speed. A certificate turns high severity with under 14 days left, and critical with under 3.

How does a website monitoring tool avoid false alarms?

A website monitoring tool avoids false alarms by asking more than one location to confirm a failure before it alerts anyone. One failed check never counts as an outage here.

Each minute, 1 of 3 probes takes its turn. If it fails, the other 2 check right away, and at least 2 of 3 have to agree before an outage is confirmed. The probes run across at least 2 hosting providers. If many unrelated sites fail from one probe, the system suspects that probe and holds the alerts.

Firewalls get their own label. A site may answer a probe with a 403 or a challenge page, so the status reads “Blocked, monitoring blind”, never “Down”. Our probe IPs are published so you can allow them.

What does a confirmed outage look like, step by step?

A confirmed outage moves from one failed check to an alert in a few clear steps, and every step is recorded. Here is an example of how one unfolds.

Probe 1 loads the homepage and gets no response. Probes 2 and 3 check straight away. Probe 2 also gets no response, so 2 of 3 agree and the outage is confirmed. The alert goes out by email and in the app, with the failure type: network.

Within the alert you see what failed, from where and when. A template explanation arrives first, then the AI explanation follows with what a network failure usually means and what to check first. When the site loads again, a recovery notice closes the loop, and the outage stays in the site's history.

What should you do when an outage alert arrives?

Begin with the failure type in the alert, because it points to the right person. DNS leads to the DNS host, SSL to the certificate and its renewal, network and server to hosting, application to the code or the latest release, and content to the page or its template.

For maintenance you expect, serve a 503 with a Retry-After header. That reply tells crawlers the break is temporary, while a maintenance page on a 200 OK can look like real content. Quiet hours and maintenance windows keep alerts in step with your schedule.

A common mistake is watching only the homepage. The homepage can load perfectly while the contact page or a key service page fails, so choose the pages that matter most to the business as critical URLs.

How do outages reach developers and clients?

Outages flow into the same loop as every other problem on the platform, so they reach the right people with proof attached.

An outage can become a ticket in the Fix Tracker, with an owner and the record of what failed. Uptime and incident history appear in the client report, next to SEO issues found and fixed. Where you run the optional Auto Recovery Agent, a confirmed outage can be matched to a pre-approved action, such as restarting a named service, for a person to approve.

How does AI help in an uptime monitor?

AI explains each confirmed outage in plain language, including the failure type and what to check first, while plain code confirms the outage itself.

That split matters at 3 in the morning. The person on call reads a clear explanation instead of decoding a raw error, and the account manager gets wording they can share with a client. Counts, times and status codes come from the stored checks, never from AI text.

Alerts never wait for AI. A template goes out first, and the AI text follows. If the AI server is slow or down, outage alerts still go out on time.

Questions, answered

How often does the uptime monitor check a site?

Page loads for the homepage and 2 critical URLs run every minute. DNS runs every 5 minutes and the SSL certificate every 6 hours. Checks for blank, error or maintenance pages run with each page load.

What counts as a confirmed outage?

An outage is confirmed when at least 2 of 3 probes agree that the site failed. One failed check never counts on its own. The alert then names the kind of failure: DNS, SSL, network, server, application or content.

Why does a firewall block not show as down?

A 403 or a challenge page means the site refused our probe, and the site may be working fine for visitors. The status reads “Blocked, monitoring blind”, so you know the monitor cannot see the site. Allowing our published probe IPs clears it.

Which pages should be critical URLs?

Pick the pages the business depends on, such as a main service page or the contact page. These checks are page loads only, so they never fill in a form or sign in. That keeps test traffic out of your enquiries and orders.

How do alerts reach me?

Alerts arrive by email and in the app, followed by a recovery notice when the site is back. Each one shows what failed, from where and when. Quiet hours and maintenance windows control when they reach you.

Can a short outage hurt rankings?

A short outage rarely causes lasting harm, because crawlers retry later. Repeated or long-lasting server errors are a stronger signal, and they can slow crawling or drop URLs from the index over time. That is why knowing about a real outage quickly is useful.

How does AI help in the uptime monitor?

AI explains each confirmed outage in plain language, with the failure type and what to check first. It never decides whether a site is down, because that takes 2 of 3 probes agreeing. Alerts go out first and never wait for AI.
