I am writing from Istanbul. Turkey is blocking Wikipedia. Wikivoyage is not blocked. Except that if you just go to www.wikivoyage.org and type in a destination, e.g., Istanbul, you will be blocked because you are sent to the Wikipedia default language redirect https://www.wikipedia.org/search-redirect.php?family=wikivoyage&search=istanbul&button=&language=en&go=Go. If you go to www.wikivoyage.org, choose english and then search for a destination it works fine. But that might not be obvious to most users. Maybe Wikivoyage should just have English as the default language as e.g., Wikivoyage has. Or WV should have its own redirect page. Or the search-redirect should be on wikimedia.

If I understand correctly, people would be able to use Wikivoyage if all requests were processed on the site, but for some reason a request is run by wikipedia.org (which is prone to censorship), so people can not access Wikivoyage content either.
I am sure that hosting the redirect on the wikipedia.org server has some technological implementation merits unknown to me, but how about changing that if it is not too costly? Allowing whole countries to access Wikivoyage/etc sounds like a huge merit to me. Thanks for considering! :-)
