I live in Turkey, and Wikipedia is blocked for some stupid reason!

But I've noticed that if I open "https://commons.wikimedia.org/wiki/Main_Page" which is not censored, I can then access Wikipedia as if it is not blocked at all, provided that I'm using the same browser.

Could anyone please explain what's happening here?


  • I think that was it, loading Wikimedia will create 2 cookies, namely CP: "H2" and GeoIP: "TR:77:Yalova:40.66:29.28:v4". Loading Wikipedia without first loading Wikimedia will fail to generate those, but if Wikimedia was loaded, then Wikipedia will use them. – Mo3tasm Sep 16 '17 at 20:02

Can you please try this again with firebug, check the cookies created on your computer when you view wikimedia, it should be there a cookie that lets you pass on the censorship. You'll have to do the dirty job, cause outside of Turkey we can't test such...

    Is there a way to make the cookies permanent? so they are used every time? – Mo3tasm Sep 16 '17 at 20:07
  • Yes mate, set it read only! ;) – Marco Sep 16 '17 at 20:08
  • How would that work? The site uses SSL, so a MITM can't check cookies. – Arminius Sep 16 '17 at 20:15
  • @Arminius I'm sorry sir but I didn't get the point of your comment. – Marco Sep 16 '17 at 20:17

    @Mo3tasm I don't doubt your observation at all. I'm just saying that this answer doesn't currently provide a plausible explanation. A government would block IPs, DNS, etc. I find it very unlikely that their censoring is based on cookies. – Arminius Sep 16 '17 at 20:36
