First of all, welcome to Turkey : )
Turkey currently does not ban access to forum. No access issues. There is probably a problem where you are connected. There are exceptions at several internet providers (kablonet, ttnet). A vast Turkish community connects every day without problems. Last year, we had access problems for a short time but it improved. There is also no legal issue or restriction regarding Bitcoin. In fact, Turkey is a paradise for crypto currencies. Because there is no legal regulation, yet.
Thanks. Are you by chance going tomorrow to Blockchain economy conference in Istambul?
I tried more locations in different regions and site didn't load.
Thanks for everyone, now I see this question was already raised.
I think to change DNS for many users is not easier than just use VPN, proxy or Tor.
I was just surprised that particularly Bitcointalk has problems of loading here..
