The two subdomains (technews and primaries) both have the same IP of 70.32.92.201, a MediaTemple IP. TechCrunch used to host at Media Temple according to DomainTools Hosting History. There is probably an A record in the DNS pointing those subdomains to those specific IPs.
The IPs have just been recycled and are being used by MediaTemple hosting customer.
Probably caused by pointing to an old IP in their DNS, which is now reused for a different site. And because that server doesnt know about that domain, it shows the default vserver:
http://70.32.92.201/
Still bad though, since they now have access to the cookies/local-storage of techcrunch.com itself.
I had a problems with a hosting provider in the past that lead to something similar happening with one of my websites.
Basically rather than explicitly binding each IP address for their servers to the server's MAC address itself they just allowed IP addresses to be assigned on the servers themselves essentially creating IP address conflicts if the same number was assigned by the administrators of 2 servers on the same LAN.
This first manifested itself when I accidentally assigned the wrong IP address to one of my servers and received angry emails telling me that I had taken someone elses site offline. Obviously I was embarrassed by this , apologized and corrected the address and didn't think much else of it.
Months later , after I had a server go down and rebooted it I found that my website was now pointing to some scam site.
Turns out that someone had got a server on the same LAN (rented or hacked I don't know) and assigned it every possible IP address just waiting for another server to go down so that they could steal the address.
I had a similar problem when doing support hosting. Static routing wasn't set up on cluster of servers and two ones with almost identical software configurations were colliding. It was particularly nasty because once you had logged in to both, you couldn't really identify which machine you were hitting.
The solution ended up being to drive to the DC, plug a monitor into the machine, and see Windows' "IP Address Conflict" dialog box on the screen >_<.
Looks like just a new owner of 70.32.92.201 where they still have some old dns records pointed..and what you see is the default vhost on new owner's site, blackoakam.com. Nothing to see here.
Are they still using these domains? Looks like they just stopped using them but didn't update the DNS records and now someone else has that IP address.
So the assumption I'm making here is that they set this (sub)domain up and had the IP as their old servers, the servers have changed hands (since they moved to Wordpress vs. self hosted) and the new owner has a wildcard host entry set up.
I took a look at the about page (http://technews.techcrunch.com/about-us/) and figured it must be satire. Then I read the comments here and it seems like these guys are real. But I still think Arrington and McWorther have a striking similarity.
