An uptime alert helps only when it reaches someone who can decide what to do. Choose the customer journey to monitor, the failure condition, escalation owner and recovery test before adding a dashboard. A homepage check alone may miss a broken checkout or enquiry form.
How to make the decision
List the critical public paths: homepage, key service page, contact form and checkout if the site sells online. Decide which are safe to probe automatically and which need a scheduled synthetic transaction. Record request frequency, failure threshold, locations, alert destination, on-call owner and backup. Test a known failure in a controlled environment, then confirm the alert arrives and is acknowledged. Keep an incident note with start time, customer impact, cause, fix and verification. Include maintenance windows so planned changes do not become noisy false alarms.
Worked example
Synthetic store: the homepage returns 200 throughout a payment outage, so the original uptime check stays green. The team adds a non-purchasing checkout-step probe and a daily controlled test order. A simulated gateway failure triggers the checkout alert, the owner acknowledges it, switches to the approved incident message and confirms recovery with a new test order. The report names the actual affected journey rather than claiming “site uptime” was 100%.
What to verify
- Does each alert identify a customer impact?
- Is there a primary and backup responder?
- Has an alert been deliberately tested?
- Is recovery verified from the customer side?
Limits and ownership
Monitoring vendors differ in how they follow redirects and evaluate response content. Check the selected tool’s behavior and avoid placing sensitive test credentials in public probes.
What to hand over
Put the alert route in a short runbook: first responder, backup, customer-impact check, status message, rollback contact and recovery test. Review it when staff change. A resolved dashboard notification is not the same as a recovered customer journey, so close incidents only after the relevant action works again.
Common question
How often should the site be checked?
Match the frequency to business risk and the tool’s cost; a store taking orders continuously needs a tighter route than a brochure page.
