Help Center Troubleshooting Problems with Ad Serving

How do I troubleshoot my ISP's nameservers?

What is a nameserver?
Nameservers are used by ISPs (eg: Comcast, Time Warner, AOL, Yahoo, AT&T, etc.) to map hostnames (eg: www.adspeed.com) to IP addresses (eg: 127.0.0.1). If a nameserver server has problems, users of these servers will experience connection problems to any/many websites. In Firefox, the error message is normally "Server Not Found". When this happens, visitors using another working nameserver would be able to access the websites normally.

Problem Identification
The following 2 images are the same file but use different method for access, one uses hostname and one uses direct IP address.

Hostname

IP Address

If you can see both images, your ISP's DNS servers seem to work properly. Otherwise, you might have an isolated problem seeing ads served by AdSpeed. To verify that your ISP nameservers are causing accessibility problems, you could ping our server or perform a nameserver lookup on g.adspeed.net. To do this in Windows:

Click on Start/Run and type "cmd"
When the command-line window appears, type "ping g.adspeed.net"
And perform a lookup of hostname "nslookup g.adspeed.net"

Solutions
If the ping/nslookup results contain any error message, you should contact your ISP and ask if they have or are aware of any issue with their nameservers. Or you can try to use another DNS server, we hear great things about OpenDNS
