    Not entirely sure why changing the DNS servers would have such an impact in the first place. So, what does the page not opening look like? Your new browser tab just stays empty?  What about the status message: Does it say something like 'waiting for facebook.com" or "loading"? (It should be stuck on some message.)

    Have you tried emptying your browser cache, or tried a different browser?

    You can execute these commands and paste the full output here so we can have a look at these as well. (Assuming Windows here, these tend to work on Mac too.)

    nslookup -type=txt debug.opendns.com.

    nslookup facebook.com.

    tracert facebook.com

    tracert fbstatic-a.akamaihd.net

    You have done everything wrong, not just the commands.

    Firstly, your computer is not configured to use OpenDNS, but to use Google DNS, so it does not make sense to even post here in this OpenDNS forum.
    http://welcome.opendns.com/

    Secondly, you did it wrong with the commands. (But the commands do not make sense if you don't use OpenDNS.)

    So, only if you're actually using OpenDNS:
    First open a command prompt window (Start > Run > cmd).  Then enter (or copy and paste) the commands maintenance has listed, including all parameters and possible trailing dots:

    nslookup -type=txt debug.opendns.com.

    nslookup facebook.com.

    tracert facebook.com

    tracert fbstatic-a.akamaihd.net

    Thanks for that.

    I have just started to go through the process of setting my router up, but i can not find my router in the list of available options.

    I have a d-link. DSL-2730B.

    How do i configure this router?

    You can check the other DLink instructions for reference, as they are similar, or even see the generic instructions. In short, the optimal setup is to configure the OpenDNS addresses as static in the WAN/Internet section of the router settings, provided that the option exists to set *only* the DNS to static/manual.

    If this is a device provided by the ISP, they may lack such configuration options.

    If I'm getting the correct manual for your copy of this router, the manual says

    To access the DNS window, click the DNS button in the Advanced directory.

    --Are you in Australia?

    Well, you certainly have a routing problem. Your ISP or one of their peers is shuffling your traffic to the US.

    I suggest opening a support ticket. Include a link to this thread. Maybe OpenDNS can get the responsible party to sort this out, which is usually the case.

    "Well, you certainly have a routing problem."

    Sure, but different than you think.

    "Your ISP or one of their peers is shuffling your traffic to the US."

    Nope.  He's using the OpenDNS Palo Alto location, and this is fed with US based information by Facebook.  The well known CDN problem again if one is very distant from the DNS service being used.  The ISP is not involved here, and they just do their routing job.

    To wait until OpenDNS has established a data center in your part of the world, i.e. around New Zealand or Australia...

    Or to temporarily use your ISP's DNS service as long as you use Facebook. Here is a quick switcher:

    Alternatively you'll have to find out all those many domain names used by Facebook and to add entries for them in your hosts file using the local Facebook IP addresses you find out by querying your ISP's DNS service.
