As I have told yesterday, undersea cables are broken, and you might be facing slow internet speed or most of the websites are not getting opened in once, you might be reloading the website once or twice.
Actually all this problem is arriving due to broken undersea cables. I have checked my blog which is not accessible on most of the systems and ISPs. So I have researched and found the solution to this problem.
The solution is as follows you have to change some settings in your Network Adapter.
If you want to access a site (say example.com) from your browser, your computer needs the IP address of the web server that is hosting that domain. The computer will then query a public DNS server to find the IP address of the site example.com.
Actually these are the IP addresses of Google DNS. i.e. Preferred DNS Server is 188.8.131.52 and Alternate DNS Server is 184.108.40.206
Select Internet Protocol Version 4 (TCP/IPv4), followed by Properties and them replace the IP addresses of your Preferred DNS server and Alternate DNS server with the IP addresses of the Google DNS servers which are 220.127.116.11 and 18.104.22.168 – the order doesn’t matter.

In the above videos, I have changed settings for an Ethernet (LAN) connection but the steps are similar for Wireless networks as well.
