Charter Implements SiteFinder-Like DNS
paulbiz writes "Charter Cable's DNS servers have just started resolving all invalid hostnames and pointing them to their own error page. The About page states: 'This service automatically eliminates many of the error pages you may encounter as you surf the web. No software was installed on your computer for this service to work.' It has an 'opt-out' page, but when you use it Charter simply sets a cookie that makes their page redirect errors to Microsoft Live Search instead!" One more reason to use OpenDNS, where you can actually opt out of the custom error page.
Every customer we set up I add openDNS as the secondary DNS in their router which act's as their DNS server. Granted you can only do this with a decent router or in our case the buffalo router with DD-WRT installed. (every customer has a DD-WRT router as we will only work with our router and not anyone elses)
Comcast is notorius for having their DNS dead and by us adding in a secondary DNS that is not ISP locked it gives them more days without problems than their neighbors.
Any geek that is not running a dd-WRT or a OpenWRT router at home is missing out.
Do not look at laser with remaining good eye.
See their site for more info.
How does OpenDNS make money?
OpenDNS makes money by offering clearly labeled advertisements alongside organic search results when the domain entered is not valid and not a typo we can fix. OpenDNS will provide additional services on top of its enhanced DNS service, and some of them may cost money. Speedy, reliable DNS will always be free.
Well Charter in particular has been blocking DNS ports to anything but their DNS servers for a long time.
So running your own resolver on a Charter line probably will basically mean no DNS.

This might be the case in certain areas, but in my neck of the woods, I'm able to use DNS servers other than standard Charter DNS resolvers just fine.

I talked to their tech support a few days ago about this shadiness. He had no idea this was going on, and rightfully thought it was a malware/spyware problem at first, until I explained a little more clearly what was going on, and he did some poking around and found other blog and forum posts about this. He seemed somewhat surprised that Charter would engage in such a practice and that no one had been told about it.
He was talking with level 2 support while he was on with me and said that they just kept telling him it was probably malware/spyware. Hilarious that they at least see it that way too, but sad that their company pulls this shit on them without telling anyone first. I asked him for a followup, he said he'd pass it along to level 2, I gave him my email address, and that was that. I don't exactly expect to ever hear back from them, so I'll probably have to make a stink at a city Cable Board meeting to get any response.
In the meantime, I hope other folks out there start repeatedly and publicly asking Charter:
- Were they ever going to make an announcement/disclosure to allow customers to opt-out, or at least tell their staff about it?
- Will they provide options for customers who don't allow or regularly clear cookies, such as a non-redirecting DNS?
- Why were they pointing people towards http://optin.charter.net/ , which doesn't exist?
- How much information do they gather about visitors to their link farm?
- Is there a third-party involved providing Charter the redirect (like Barefruit did for Earthlink?)
- How much money are they making from their link farm affiliates?
- Most importantly, do we have any guarantees that they aren't redirecting or degrading other network traffic?
In the meantime, I've switched my DNS over to Level3 (4.2.2.2 and 4.2.2.3).
I'm not surprised ISPs are doing this. More will be doing this. What does surprise me is how ISPs try to do this silently and behind closed-door without informing their customers, or even their tech support in some cases.
Think about it this way: Any change an ISP makes that results in 1% (or more) of their customer base calling in for technical support is a cost nightmare. Customer Service is a (*the*) major cost center for ISPs. I guess we have to imagine that they are making more money than the pain of doing the customer service is costing them.
The other thing that surprises me (and obviously I'm biased since I run OpenDNS) is that the search results page linked above is 100% ad-driven. There are no no organic search results for my typo (as far as I can tell). Moreover, when I click on a category to "refine" my results they totally remove the typo'd domain that I had there in the first place instead just giving me generic ads for a category (which is a mediocre CPC on their side) and a crappy search experience on the user side. There is absolutely no user-benefit to what Charter has done here.
I'm proud to say that our page is getting better and better every single day. Compare and contrast. Not only that, but we're driving more and more innovation in both user navigation and fundamental DNS operations. These things go hand in hand. Fundamentally the DNS is about navigation. It's about helping users get where they are trying to go. That's exactly what we intend to help our users do. We know that the changes we have made to how our DNS servers operate aren't for every user which is why we are so clear about how our system works and is why make sure we can manage account settings on a per IP basis (CIDR-style preferences down to
As usual, I'm happy to answer questions where I can.

# Hack the planet, it's important.
As a frequently-disgruntled Charter customer, I was given a golden ticket. I feel obliged to share it:

IWARS.
People, in general, disappoint me. Politicians even more so.
