How To Spot A Blogspot Blog (A Quick Fix)

Say it five times fast. Go on.

I just posted this over at Lost Laowai, and as much as I’ve made a commitment to not cross-post – I thought this was pretty useful and as I can’t seem to get all my readers here to be faithful readers there (despite having a bunch of new authors, great topics, a pretty design, free guppies for the first 100 visitors…) here’s the original post:


greatfirewallsml.jpgLast November I wrote a post with a collection of “tools” to help you get around the GFC. At the time of writing (literally within hours) Blogspot were released from their “blocked” status in China, and so there wasn’t much use for the otherwise useful PK Blogs site.

A few months on, my predictions of tides changing and it again being blocked have come true. I was slow to post about this because really… it’s just not very interesting anymore. The blocking and unblocking of Blogspot, Wikipedia, BBC News, etc., used to be mysterious, nefarious even. The validations of fears that the CPC was watching us. Sort of a 1984 meets 1989.

Now however, it’s just ‘life here’. It’s annoying, childish and … annoying. I visit a number of Blogspot blogs and this kinks my visitation rights. I am fickle about reading online and often can’t be bothered to go through a proxy service (like those mentioned previously).

That said, Ya I Yee, an interesting new Chinese blog (written in English), has a cool little trick to thwart the Wall seamlessly and visit all the Blogspot blogs you want (note, these instructions are for Firefox – which you should be using anyway).

The Blogspot blog block quick fix:

Use Notepad (or any plain text editor) to write a file with the following codes:

function FindProxyForURL(url,host){
    if(dnsDomainIs(host, "")){
    return "PROXY";
    if(dnsDomainIs(host, "")){
    return "PROXY";

Save the file as proxy.pac (note, be careful Notepad doesn’t add a .txt extension to the file) and put it in your root directory (usually C:\). In Firefox, click Tools->Options->Advanced->Network->Settings… fill the text below in the blank under “Automatic proxy configuration URL”:


Press Reload on the right, press OK, and OK. Relaunch Firefox, and you’re done! Free to surf Blogspot (and the continually blocked till your heart’s content.

Thanks a lot to Yee and Fermi Zhang for this script.

  1. It works great, but I want to know how it works, because I want to know if I can set a proxy for Livejournal, which, as I’m sure you know, has been blocked of late. I also did a reverse lookup on the two IP addresses, and found that the first (for blogspot) is, and the second (for WordPress) is So, I either don’t understand how the proxies work, or I don’t understand how the Great Firewall works, or, most likely, both. I tried setting similar lines for Livejournal’s IP address, i.e.:

    if(dnsDomainIs(host, "")){
    return "PROXY";

    Needless to say, that didn’t work. I tried several other things too, but didn’t have any luck. Any ideas?

  2. well,it’s simple to explain how it works.

    according to the Fermi Zhang’s explanation,both domain names of and has multiple IPs and GFW just blocked the default one.That means when you use the trick above,it will redirect the domain name to the backup ip that hasn’t been blocked.

    So Tim’s saying it not 100% right,blogspot now belong to google so its backup ip is google.And it’s same to,if anyone can find’s backup ip then we can fix it!

  3. Hi all, I’ve updated the proxy.pac script in my blog. LiveJournal and Wikipedia are both available with the new one, just check it out by clicking here. Regards!
