When websites are unavailable, you can change the situation with the help of certain settings. There are many reasons for this phenomenon, and the troubleshooting procedure depends on the characteristics of a particular site, browser and Internet connection.
If all sites are unavailable, check your internet connection settings. Change the installed options by opening the "Internet Options" menu. Errors when opening pages can occur due to your hardware - check your modem.
The site page may be unavailable due to low internet speed - try installing a different browser. Their performance is different, and this is one of the most important parameters for working in the global network. In addition, some browsers may block content from unwanted sites.
Check the software installed on your computer. Some of the programs can also block web pages. Check your Windows firewall settings - set a different permission mode, create a rule for connections. If there is no antivirus installed on the computer, then the opening of sites can be blocked by the virus.
If you are the owner of an unavailable site, check the end period of your prepaid hosting service. The decision to close your site could have been made by the server administration. If, by entering your personal data into your account, you cannot get to the site, it is possible that you have violated the rules of the resource and the site has become inaccessible to you.
You have checked all the parameters, the period of paid hosting is not over yet, you have not violated the rules, then the DOS Attack (Distributed Denial of Service) could become the reason for the inaccessibility of the site.
The number of Internet users is growing, as is the number of fraudsters. Initially, the DOS attack was used to test the reliability of communication channels and the robustness of systems. However, this defense strategy has become a problem that is being addressed through a variety of methods. Protection from such attacks should be present on any resource, regardless of its size.
