I am in Ecuador, today we have a crucial debate where a package of constitutional amendments will be approved (all of them are quite medieval like declaring that all communications are a public service). Anyway, I am trying to understand how do they block selected images and videos. All blocked assets give 504 errors like this one for example:<p>GET https:&#x2F;&#x2F;pbs.twimg.com&#x2F;media&#x2F;CVTvltlXIAAWbEH.jpg 504 (Gateway Timeout)<p>Do they have a proxy installed where traffic from given CDNs is tunneled before entering local ISPs and they actually &quot;watch, select and dump&quot; the images&#x2F;videos that need to be blocked?<p>Is Twitter involved?
Ask HN: How is my government blocking images and videos on Twitter?
