Live HTTP check from NovaVerb infrastructure. The result identifies where its evidence came from.
Monitor website availability, HTTP status code, and server response time history. Instant live status check with no account required.
Een live bord van de sites die iedereen in de gaten houdt - up, traag of down, continu ververst. Elke status is een echte server-side controle, nooit verzonnen. Dien elk openbaar domein hierboven in om het toe te voegen.
Geen site die overeenkomt met je zoekopdracht.
This check proves whether one address answered one HTTP request at one moment, and which status class it returned. It is a point-in-time reachability result, not uptime: a site that is down for three minutes an hour will usually pass, and a site that answers here can still be failing for visitors on another network.
Live HTTP check from NovaVerb infrastructure. The result identifies where its evidence came from.
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.
Gebruik de bevinding om een probleem te verifiëren, verbind vervolgens een werkruimte wanneer je geschiedenis, monitoring of site-brede analyse nodig hebt.
Een monitor is nuttig omdat één succesvolle aanvraag slechts een momentopname is. NovaVerb slaat elke voltooide gratis controle voor de URL op, zodat je kunt zien of status en responstijd stabiel zijn over herhaalde monsters.
Het is geen 24/7 wereldwijde uptime SLA, een browserprestatie test of monitoring van echte gebruikers. Voor geplande controles, waarschuwingen, monitoring op meerdere locaties en lange termijn rapporten, verbind de URL met een Novaverb werkruimte.
Een server die reageert - zelfs met een 4xx zoals 403, 401 of 429 - wordt behandeld als UP; alleen geen enkele reactie (timeout, DNS-fout of geweigerde verbinding) of een 5xx-serverfout telt als down. Elke controle is een enkele aanvraag van Novaverb, geen wereldwijde SLA.
Submit the public address you want to reach. Scheme, www and path are normalised before the request. A private host is refused. Reading a single successful check as an uptime guarantee is the mistake this section exists to prevent, and continuous monitoring with a recorded history is a workspace feature rather than a free one.

Status classes are then classified honestly: 2xx and 3xx as reachable, 4xx and 5xx as a problem, and a timeout as unreachable. One request produces one result, and it is labelled as a point-in-time observation.
RFC 9110 defines HTTP semantics, including what each status class means, and the classification above follows it rather than a house interpretation. That is why a 301 is reported as reachable: the specification defines a redirect as a successful response that names another location, and calling it downtime would misreport the server.

Lees de specificatieEach 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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
