Monitor history

Every completed public check is retained as an evidence sample. This history grows when the URL is checked again; scheduled alerts and continuous monitoring belong to a connected workspace.

Evidence model

Know what the result proves

Each free check separates measured evidence from interpretation, and interpretation from the deeper work available in a connected workspace.

1. Source

Live HTTP check from NovaVerb infrastructure. The result identifies where its evidence came from.

2. Boundary

Each check is a single server-side HTTP request from NovaVerb. It is not a global uptime SLA, browser performance test, or proof that every visitor can reach the site.

Website monitoring explained

Keep a measured history of availability

A monitor is useful because one successful request is only a snapshot. NovaVerb stores each completed free check for the URL so you can see whether status and response time are stable across repeated samples.

What the free monitor proves

Whether the target returned an HTTP response during this check.
The status code, response time and final URL observed by the server-side probe.
A history of measured samples for the exact URL submitted.

What it does not prove

It is not a 24/7 global uptime SLA, a browser performance test or real-user monitoring. For scheduled checks, alerts, multi-location monitoring and long-term reports, connect the URL to a Novaverb workspace.

A server that responds — even with a 4xx such as 403, 401 or 429 — is treated as UP; only no response at all (timeout, DNS failure or refused connection) or a 5xx server error counts as down. Each check is a single request from Novaverb, not a global SLA.

What to submit — and what to avoid

The check is only as honest as its input. These examples keep you out of the two mistakes that produce a misleading result.

check_circleUse it like this

yourdomain.comAny public address form works. http or https, with or without www, a bare domain or a full path — we normalize it for you.

https://yourdomain.com/healthA stable public URL whose HTTP status reliably reflects up or down.

cancelAvoid this

A page requiring loginAn authenticated page returns 401/403 to an anonymous probe, so it would read as 'down'.

Expecting continuous uptime historyThis is one point-in-time check; ongoing monitoring is a connected-workspace feature.

Public methodology

Exactly how this result is produced

No opaque score. Every result comes from these steps — so you can trust it, reproduce it, and explain it to a client.

We normalize the address and issue a standard HTTP request, reading the response status code.
We classify by status class: 2xx/3xx as reachable, 4xx/5xx as a problem, timeout as unreachable.
We report a single point-in-time result; continuous uptime monitoring is a workspace feature.

Built on public standards

The international standards this check applies

Novaverb measures your site against these published specifications — not an opaque score. Each card names the standard, the body that maintains it, and exactly how this tool applies it.

HTTP Semantics — status codes

Interprets each response by its standard HTTP status class (2xx up, 5xx down).

Read the specification open_in_new

verifiedWe list a standard only where this tool genuinely reads or measures against it. Where a signal is outside a live check, the result says so instead of implying coverage.

Common questions

Website Monitor FAQ

What does the Novaverb Website Monitor check?

Each run sends one live HTTP request from Novaverb infrastructure and reports the HTTP status code, response time, and final URL after redirects, then stores a history of these measured checks over time.

Is this a guaranteed uptime SLA or monitoring service?

No. Each check is a single server-side HTTP request from one location. It indicates whether the site responded to that request; it is not a contractual uptime SLA or proof that every visitor everywhere can reach the site.

What do the HTTP status codes in the results mean?

A 200 means the request succeeded. A 3xx is a redirect (the final URL shows where it landed), 4xx indicates a client error like 404 not found, and 5xx signals a server-side error worth investigating immediately.

Why does the monitor show a different final URL than I entered?

Because it follows redirects and reports where the request ultimately resolved. If you entered an HTTP or non-www address, the final URL reveals your canonical HTTPS or www destination, which is useful for spotting redirect chains or loops.

What is a good response time in the monitor?

For a single server-side request, under 500 milliseconds is healthy and under 200 milliseconds is excellent. Rising response times across the stored history often precede outages and are worth investigating before status codes start failing.

How is this monitor different from the performance or speed tests?

The monitor repeatedly records status, response time, and final URL to build an availability history. The performance and speed tests break one request into DNS, TCP, TLS, and TTFB stages for deeper diagnosis rather than ongoing tracking.

Does a passing check mean all my visitors can reach the site?

No. It confirms one location got a response at one moment. Regional network issues, DNS problems, or per-user routing could still block some visitors, so treat a passing check as a strong signal, not universal proof.

How often should I monitor my website?

Frequently enough to catch outages before customers do; many teams check every few minutes for critical sites. More frequent checks build a denser history, making it easier to correlate slowdowns and failures with deployments or traffic spikes.

What should I do when the monitor reports a 5xx error?

A 5xx means your server failed to fulfil the request. Check application logs, database connectivity, and recent deployments, and confirm the origin is running. Recurring 5xx responses in the history point to instability rather than a one-off blip.

Why does website availability matter for SEO?

If Googlebot requests a page and repeatedly receives errors or timeouts, crawling stalls and rankings can slip. Reliable responses and fast status keep pages crawlable and indexable, protecting the visibility that downtime and server errors quietly erode.
