Monthly Uptime Review Checklist
A monthly uptime review documents whether your websites were available during the past month, how long any downtime lasted, and what actions were taken. For agencies delivering care plans, this review is a core deliverable that demonstrates monitoring is active. This guide provides a checklist for conducting monthly uptime reviews efficiently. This expanded guide explains the practical monitoring workflow behind the topic, who should use it, what to check, how to document findings, and how to turn website health signals into useful client, developer, API, CLI, or AI-agent workflows without overstating what monitoring can prove.
What a monthly uptime review should cover
A monthly uptime review answers three questions: was the site available during the reporting period, how long was any downtime, and what caused it. The review should also show the uptime percentage and include response time data, because a site can be technically 'up' while responding so slowly that visitors cannot use it.
Uptime percentage is calculated as: (Total time - Downtime) / Total time × 100. For a 30-day month (43,200 minutes), 99.9% uptime allows approximately 43 minutes of downtime.
The review should document each incident with start time, end time, duration, impact, root cause, and resolution. This level of detail demonstrates that incidents are investigated and resolved systematically.
Monthly uptime review checklist
Calculate uptime percentage for each site. Review the check history for the month and count how many checks passed versus failed. Calculate the percentage and compare it to the target (typically 99.9% for business websites).
Document each downtime incident. For each incident, record: date and time, duration, impact (what visitors experienced), root cause, and resolution. If the incident was caused by a third party (hosting provider, DNS provider), note this.
Review response time data. Calculate average, minimum, and maximum response times for the month. Compare to baseline values and note any significant changes. Response time trends help identify performance degradation before it becomes a visitor-facing problem.
Identify patterns. If the same type of incident recurs monthly, there is a process gap that can be addressed. If downtime consistently occurs during specific windows (maintenance, traffic peaks), note this for planning.
Compile findings into a client report. Include uptime percentage, incident log, response time summary, and any actions taken. For incidents with no issues, note that all checks passed and the site maintained healthy availability.
Schedule follow-up actions. If any incidents require ongoing investigation or if response time degradation needs monitoring, schedule follow-up checks for the coming month.
Presenting uptime data to clients
Uptime percentage is a familiar metric. Present it prominently: '99.95% uptime this month.' Provide context by noting the industry standard or the target agreed upon in the care plan.
When incidents occur, be transparent. Document what happened, when it was detected, how long it lasted, and what was done. Clients appreciate honesty and systematic response.
For incidents caused by third parties, note this in the report. Clients understand some factors are outside your control, but they want to know you detected the issue quickly and coordinated resolution.
Response time data provides context beyond uptime percentage. Present it with targets: 'Average response time: 340ms (target: under 500ms).'
Common mistakes in uptime reviews
Not calculating uptime percentage correctly is a common mistake. Use the standard formula and be consistent. If you exclude scheduled maintenance, note this in the report.
Minimizing incidents or not documenting them is another mistake. Clients appreciate transparency. Documenting incidents demonstrates that monitoring is active.
Not including response time data is a third mistake. Uptime percentage alone does not tell the full story. A site with 100% uptime but slow response times is not providing a good experience.
Not comparing against targets is a fourth mistake. If the care plan specifies a 99.9% uptime target, the report should show whether this target was met.
How MonitorMojo helps with uptime reviews
MonitorMojo records reachability status and response time with every health check. The check history provides the data needed for uptime reviews. The multi-site dashboard lets you review availability across all client sites from one view.
Each check result includes the timestamp, status, and response time. This structured data can be referenced directly in reports. For agencies, running checks on a regular cadence provides consistent data for monthly reporting.
The results depend on hosting, DNS, infrastructure, configuration, traffic, and response process. MonitorMojo helps you see what is happening from outside the hosting environment.
What this workflow means
Monthly Uptime Review Checklist is best understood as a repeatable website health workflow, not a promise that every outage or configuration issue will be avoided. Get a monthly uptime review checklist for tracking website availability, calculating uptime percentage, and documenting incidents. Perfect for agencies delivering client reports.
In practice, this workflow centers on reachability, HTTP status, downtime triage, stakeholder updates, and confirmation checks. Each check is planning input: it can show that the site is reachable, that a certificate has a given expiry window, that response time has shifted, or that a header is missing. It cannot prove root cause by itself or replace a human response. The value is in making the review consistent enough that site owners and small teams can spot issues before someone downstream has to ask about them.
Who should use this

Beyond that primary audience, the same checks are reusable by anyone with a public-facing URL that matters to revenue, leads, or reputation: a recurring review is cheap insurance compared to hearing about the problem from a client or customer first.
Step-by-step monitoring workflow
Start by listing the URLs that actually matter instead of just the homepage — for a small team doing a routine check before something breaks in front of a visitor, that usually means the pages tied to revenue, signups, or trust, not every page on the site.
Next, define the check types for each URL: reachability, HTTP status, HTTPS/SSL certificate status and expiry window, response time, redirect behavior, and security header presence. For API, CLI, and AI-agent workflows, document which endpoint or command runs the check and where the result is stored.
Set a cadence that matches the risk — a low-traffic page may only need a monthly look, while a page tied to revenue or signups deserves a check after every deployment and before any campaign or launch.
Record what you find with a consistent format: URL, check type, status, issue, owner, detected date, and next review date. Then say what actually happened in plain language — a check can surface a symptom, but site owners and small teams still need to confirm the cause.
- Choose the URLs that matter most to visitors, clients, revenue, and operations.
- Run uptime, SSL, response time, and security header checks on a consistent schedule.
- Triage failed or risky checks by likely owner: hosting, DNS, SSL, code, platform, or third party.
- Record notes in a repeatable format so future reviews do not start from scratch.
- Send a plain-language summary with the issue, impact, owner, and next review date.
- Run a confirmation check after remediation so there is an external result to reference.
Checklist or template
Use this template for recurring reviews: [URL], [Check Type], [Status], [Issue], [Priority], [Owner], [Detected Date], [Resolved Date], [Next Review Date]. Add a one-line summary at the top: what changed, what needs attention, and who owns the next step.
For site owners and small teams, group findings into the four signals that matter most: reachability, SSL status, response time, and security headers. Where nothing needs action, say the check found no issue in that area rather than implying full coverage.
- [URL]: the exact page or endpoint checked.
- [Check Type]: uptime, SSL, response time, headers, API, CLI, or agent workflow.
- [Status]: pass, review, failed, blocked, or needs human investigation.
- [Issue]: the observable symptom, not an unsupported root-cause claim.
- [Owner]: agency, developer, host, DNS provider, client, or third-party vendor.
- [Next Review Date]: when the team should confirm status again.
Common mistakes
The most common mistake is monitoring only the homepage while a checkout, signup, or booking flow silently breaks. Another is assuming SSL auto-renewal always works — it can fail quietly, and an external check is the only way to catch that before a browser warning does.
For site owners and small teams specifically, the recurring miss is treating one clean check as proof the whole site is fine, or fixing an issue without ever writing down what happened — which means the next person repeats the same investigation from zero.
- Tracking too many low-value URLs while missing the ones that matter.
- Skipping notes after an issue is resolved.
- Reporting a status without an owner or next step attached.
- Assuming automation can resolve an incident without human review.
- Treating one clean check as proof that every risk is covered.
Practical example
Consider a small team doing a routine check before something breaks in front of a visitor. A scheduled check flags that the site is slower than its usual baseline and that a security header is missing. Instead of guessing, the team logs the observation with a timestamp, assigns an owner, and re-checks after the fix ships — turning a vague "something feels off" into a specific, closed-loop task.
How MonitorMojo helps
MonitorMojo runs website health checks that combine reachability, SSL certificate status, response time, and security header presence in one workspace, so this workflow doesn't require stitching together several separate tools.
The API and CLI make the same checks scriptable for site owners and small teams who want them wired into an existing process, while credit-based checks keep it practical to run reviews exactly when they matter — before a client call, after a deploy, or when someone asks whether the site is healthy. Results still depend on hosting, DNS, and how quickly the responsible team acts on what the check finds.

Frequently Asked Questions
How is uptime percentage calculated?
Uptime percentage = (Total time - Downtime) / Total time × 100. For a 30-day month, 99.9% uptime allows approximately 43 minutes of downtime.
Should I include response time in uptime reviews?
Yes. Uptime percentage alone does not tell the full story. Response time data provides context about site performance.
How do I handle third-party incidents?
Document the incident, note it was caused by a third party, and explain what was done to coordinate resolution.
What uptime percentage should I target?
99.9% is common for business websites, allowing about 8.7 hours of downtime per year. The right target depends on business criticality.
How often should I send uptime reports?
Monthly is standard for care plan clients. This aligns with monthly billing and provides regular touchpoints.
Can this prevent every issue with the site?
No. Monitoring helps site owners and small teams detect website health signals and organize follow-up, but it does not prevent every outage, SSL issue, slow response, or third-party failure. The result still depends on hosting, DNS, infrastructure, and how quickly the responsible team investigates and responds.
