HTTP 451 Unavailable

Yes wordpress wud block on global server.

What I mean is Government is not going to ask individual hosts to block pages but instead it will send "takedown" notice.

If there are big international providers where "takedown" notice can not be sent in that case it will block on ISP level and shud ask ISP to send 451.

That's the thing, HTTP status codes are sent by the web servers themselves, ISP (or the govt) cannot "send" http status codes it is part of the text data returned by individual websites themselves, like HTTP header, then HTTP body which contains the actual webpages...

If a govt asks website to block webpages and they agree then they (the websites) will send HTTP 451 error code, if they don't agree (rogue websites) then govt asks ISPs to block the website/URL itself - either no response or the common message presented by ISP something like "This website has been blocked by order of govt blah blah"
