Some of my customers have complained that they were unable to access my site. They complained that the site was accessible by IP address (72.36.134.131) but not by domain name - http://blog.taragana.com/. I couldn't put a finger to it as my DNS servers as well as the site is running perfectly. I verified that both of them are accessible across the globe. Scott Goldblatt kindly explored the issue for me and found out that Time Warner Cable DNS servers are blocking my site! He also found that other users of Times Warner Cable in USA are facing the same problem in accessing my site.

I am totally at a loss as to why Times Warner Cable would do it. My blog is very technical and very safe even for kids and without any trace of any illegal elements. I would be grateful to my readers if you could kindly explore the issue and shed some light on it.

Secondly I would want to request Time Warner Cable users to consider using OpenDNS to access the internet. It is safe, fast and free DNS service and doesn't discriminate like Times Warner Cable did with my site. You can start using OpenDNS by setting your DNS server addresses to 208.67.222.222 and 208.67.220.220. Here is a simple guide to using OpenDNS and here is their FAQ.
May I also request you to consider lodging a complaint to Times Warner Cable. They are more likely to listen to you as (you are) their customer.

I am currently exploring, without any success whatsoever, the Times Warner Cable site looking for avenues for complaining.

This brings to mind a bigger issue of restriction of freedom (think China) and content by (ab)using the DNS servers. While this won't deter the dedicated and tech-savvy users, it will prevent 99% of users from accessing the target site. Most users will give up as they will deem that the server is down. Few understand the differences of the message that is the server is unreachable versus the server is down.
