It just says 502 Bad Gateway. I’m not even sure if the block is intentional on their part, or a server issue of some sort.
A 502 status code does sound more like an error from the server, yes. The correct HTTP status code for a block by the government would be 451. But I’m not sure if countries that try to block social media respect this, they probably want to hide the fact that that website exists entirely. So they might go for a 404 error instead.
404 is still a server response, so I imagine no response at all would be the way to go.
Yea true, so you would just get a timeout (or an error from the DNS server that the domain does not exist if you use a ‘government approved’ DNS server.
