You end up with a site that loads both partially and slowly, at times taking upwards of 30 seconds What are infrastructure-related issues when it comes to China? What happens when your site has blocked or slow-loading resources? Note that by 35 seconds, only 30% of this website's resources have successfully loaded. I) impacts the functionality of a site when, after multiple attempts, the site or parts of its content doesn't load at all.īelow is an example of a waterfall chart when a China visitor attempted to load resources past Facebook trackers. I) interfere with the total loading time of the website in China, but also As a result, the loading process get's 'stuck'. When a browser attempts to load a blocked resource, the web browser will keep trying to retrieve the file for a period of time before it moves onto the next resource. The web browser reads HTML files to identify where to find resourcesīrowser requests resources - including images, CSS, and js files - from the server(s)įinally, the browser then renders (or displays) the webpage The web server provides HTML to a web browser to read What happens when the browser attempts to load blocked or slow technologies from China?įirst, a little background on how websites generally load. third-party resources which are hosted and managed by third party providers (e.g.

Other primary and or third party resources*, while not blocked or inaccessible in China - may be delivered from networks that perform slowly in China (i.e. This includes essential libraries widely used by developers globally, popular plugins, and or default components that website building platforms inherently include out of the box. There are a number of technologies that are blocked or slow to load in China. What are code-based issues when it comes to China? With this in mind, let's break down the technical reasons behind this behavior. Thees issues are most commonly a result of building those websites with code, plugins and third party resources that are incompatible with the Chinese internet and a infrastructural set-up that does not perform well from China.
