I was trying to post a question on Stackoverflow but got redirected to the Human Verification page. The problem is that the CAPTCHA never loads here in China, it just times out after 4 minutes. Probably because it comes from Google and Google servers are often blocked here (see screenshot below).
Stackoverflow in general works great here however being prevented from asking questions just because of a CAPTCHA that never loads is a bit frustrating (though obviously the only responsible here is the Chinese firewall).
Is there anything SO could do to allow users from countries like China to post questions? The CAPTCHA is such a critical part of it that it's a pity it depends on a third-party that doesn't load in some countries. Why not host the CAPTCHA on stackoverflow.com? Alternatively, why not offer an alternative for users who cannot see the CAPTCHA? Maybe an email confirmation or something similar?
