Tools for your website

Is your website working for your customers?

See your website from different locations. A single check helps distinguish a local connection issue from a problem other visitors can see too.

Where to check from

Choose 1–5 locations in the countries and cities you need. One run with selected locations counts as one check.

A security check runs before starting. It is usually invisible.

From a check to a solution

Website unavailable. What next?

One location provides a single perspective. Compare several locations, then investigate the cause.

01

An issue in one location

Routing, filtering or a temporary failure may be involved. Compare results and check again later.

02

Failures in multiple locations

Check DNS and HTTPS, then the server and application. A single test cannot establish the exact cause.

Clear diagnostics

One address. More than one perspective.

A website may work for you but fail to respond in another region. Choose available locations on the map and compare the results. Each check is a snapshot at the time of the request, rather than continuous website monitoring.

    Compare responses

    See where the site responded and where an error occurred. Revisit the saved result to compare conditions after a change.

Questions and answers

What to know

Why does the site work for me but not for my customer?

Access depends on the visitor’s network, DNS, the route to the server and website protection settings. Testing from several locations helps establish the scope of a problem. Finding the exact cause may also require server logs and additional checks.

How many checks can I run?

You can run up to five website checks per day for your network without signing in, with up to five locations per check. The tool shows your remaining allowance, which resets at 00:00 Moscow time. Viewing saved results does not use your allowance.

Does a successful check mean the whole website works?

No. A successful response confirms that the specified address was reachable from that location at that moment. It does not guarantee that checkout, sign-in, payments or other visitor journeys work correctly.

Why do results differ between locations?

Each location has its own network route to the website. Differences can come from geography, network restrictions, DNS or protection rules. An error from one location does not prove the site is unavailable to everyone.

Where can I find previous checks?

Without signing in, results are kept for 30 days in this browser. Account history is kept for 365 days. Open a saved check to review its date, address and responses from the selected locations.

Website availability testing across regions

When a website will not open, the first step is to understand where the issue occurs. An online availability check sends requests from selected locations so you can compare their responses. This is useful after a migration, DNS or protection changes, or a customer report that the site is unreachable.

From a test result to getting things working

Keep the check time and the locations reporting errors: these details help match the result to server events. If responses are inconsistent, our team can review configuration, load and technical faults, then propose work that addresses the identified cause.
