Hello Experts,<br />
I changed Internet Service Provider but now websites take too long to load, some up to a minute. I updated the WAN IP's on my firewall and added the secondary IP's. I am using Google public DNS addresses but it is going really slow.<br />
<br />
Please help.

Websites take too long to load after ISP change

The Domain Name System (DNS) is a hierarchical, globally distributed system responsible for associating the name of a computer, service or other resource into an IP address for connecting to the Internet or a private network. Most prominently, it translates domain names to the numerical IP addresses needed for the purpose of computer services and devices worldwide.
