If you ping and/or traceroute to a certain destination and you pings and /or traceroutes don't get anywhere or you receive timeouts that might mean that you have ran out of data. If you get a response to the destination it means there's a problem with DNS and you should check your router and PC settings if DNS is set to automatic and not static. Once you have made sure that DNS settings are set to automatic and the problem persists, take your Destination IP and type it in the address bar on the browser to see if you can get to the website of the destination server. If you get to a site contact us and we will be able to assist you further. Another way to check if the problem is DNS retated is by testing the DNS using Google's DNS servers. In your router you now need to change from automatic DNS to Static DNS and add the Google's DNS manually, if it works with Google's DNS it means there's a problem somewhere and we need to sort it out.
Google Primary DNS: 18.104.22.168
Google Secondary DNS: 22.214.171.124
