About the website accessibility checker
It is often necessary to check the availability of a website at the moment. To do this, we have developed a tool for checking the website available on the Internet from several locations. If your site is not accessible from only one location, there may be connection problems in a particular region. But your site is working and available to users.
What do server response codes mean? By them, you understand the availability of the site on the network. Depending on the situation, the server gives a response in the code form. There are about 100 such codes in total, but there are only a few of the most common ones, they are in the table above. The ideal situation is when the server returns a 200 OK status. This means that the request was processed, the page is available for users. The site performance depends on many factors: the hosting provider and local channels, global or regional networks. The regional policy of some countries prohibits or restricts the display of sites in their region. All this is important when you analyze the availability of the website. Your site may be working, but inaccessible in one location. In this case, you should not worry.
If you want to track permanent server response codes, the availability of your site, we recommend you add the website to permanent monitoring. The system will send you notifications about problems, and you can be aware of the availability of the site.
Testing the website performance is useful to do immediately as soon as you notice that it is unavailable. So you will know the reason and be able to fix it. Why is online checking by an extra service an essential step in determining the cause? If you contact the hosting provider, you will lose time, and you may also receive a response about the website's availability. So, it is better to immediately get confirmation that the site is not available from all locations. This speeds up the solution to your request.
