Website is down (Cannot load any website)

Maybe the obstacle that prevents you from accessing a certain website is the great amount of cookies and cache files stored in your device.

To learn how to clear the browser's cache (and cookies), check out the don't know how to clear the cache solutions.

It's possible that the browser itself prevents you from browsing the net and loading websites. A simple restart of the browser program itself could solve the problem.

To restart the browser click the X icon in the top-right corner of the browser (or in the top-left on Mac OS), and click the browser icon from the desktop. Try loading the same website again.

Maybe the website is down because of an ISP- or hosting-related issue. Try again in 10-30 minutes to check if it's back online. If it's still offline, report the issue to the hosting provider which will resolve it quickly.

Maybe your computer is preventing you from opening the website. Most likely it's a result of a browser-related issue (a plug-in or an extension became unresponsive), or a software-related one.

Try closing the browser first. If that didn't work, restart the computer.

Maybe there is an issue with your internet connection which is due to the ISP itself (a problem with the ISP's DNS settings or something else), which prevents you from loading any website (or only a certain website).

Call your internet service provider whose team will troubleshoot and resolve the problem as soon as possible.

When you type an address into your web browser, your computer uses DNS (Domain Name System) to look up and translate that address into a computer-friendly IP address. In other words, the DNS has the role of a librarian, who you can ask for a book. Sometimes, the servers your computer uses to look up that information can go down, thus preventing you from loading the desired web site.

Pingdom is a service that tracks the uptime, downtime, and performance of websites. Pingdom monitors websites from multiple locations globally so that it can distinguish genuine downtime from routing and access problems.

Pingdom may not help you to "wake up" your website again, but it can alert you quickly if it happens in the future.

Go to Pingdom, select and subscribe to a plan and Pingdom will start monitoring your website.

If your website goes down frequently after you have updated a component of it (a plug-in, add-on etc.), or if your host upgraded the OS or made a modification of any kind, then the update itself caused the problem.

Although hosting operators attempt to ensure Ruby, Python, MySQL, PHP, PostgreSQL, etc. remain backward compatible, some files (commands) might have been affected, which caused the website to go down.

Reverse those changes if you made them by yourself (i.e. find the faulty component and reverse the update or even uninstall it), or talk to the hosting operators.

Note: Fixing this issue might take you a lot of time and concentration. Don't modify anything unless you know it's function.

Temporary problems with your modem, router, switch, or other network device could be the reason, esp. if you see a 504 Gateway Timeout error message.

The easiest way to restart the above-mentioned devices is by unplugging them from the power outlet and plug them back in, in about 5 minutes.

If you use a router and you cannot load any website, probably the router itself is the issue. Maybe the Internet connection crashed and the router failed to re-connect or maybe it was something else that caused the router to stop working properly.

Restart the router by unplugging it from the power outlet (the easiest way), or by pressing the Power ON/OFF button (if available). Wait for 30 seconds to ensure all the power is gone and then plug it back in (or turn the power button on) again. After that, wait until the router reconnects to the Internet again.

Maybe a virus is preventing your browser from working properly or is slowing down your Internet speed and it seems that the website (or all websites) is down.
