CTC was bought by Windstream and as evidence that they've started converting the CTC network to Windstream, when I went to a down website today, I was redirected to ww23.entry-not-found.com. Since it's Windstream branded and other people have reported it, I don't think I've been rooted. I have already complained.

If you're concerned about your DNS having the same problem, for now I apt-get install bind9 and changed my DNS from my dd-wrt box (which is using Windstream DNS servers) to 127.0.0.1.

Then in /etc/hosts I set entry-not-found.com and ww23.entry-not-found.com to resolve to 127.0.0.1.

When I asked Windstream about it, they offered an opt-out alternative:

In response to your concern, Windstream recently implemented a new feature to aid the majority of our customers experiencing issues while browsing websites. When a customer types in an incorrect web address, this feature now redirects the customer to a list of possible websites they were trying to access instead of giving the generic "Page Cannot Be Displayed." Because a majority of our customers thought to believe our service had disconnected, this change was made. However, we have seen a few examples with this that is causing a small part of our customers to be unable to access specific sites. Currently, the only way to bypass this feature is to set the opt out DNS servers into your Local Area Connection. The DNS servers are as follows:

Primary DNS Server: 166.102.165.32
Secondary DNS Server: 207.91.5.32
