CDN Coverage in China

CDN points of presence (or POPs) are what keep your videos speedy by caching content at the closest available server to the viewer.

This ensures that, wherever your viewers are in the world, their videos are delivered from the server nearest to them. By adding POPs on the Chinese mainland to our network, you should see the delivery of your videos, in the usual speedy fashion, to a whole new part of the globe.

Why should I care?

Usually, if a viewer’s a long way from a POP, the latency on their connection will increase. Think of latency as simply being how long it takes to ask for a piece of data and receive it back. The further you are from the server, the more intermediary points the request and the response have to go through, in order to get from A to B. No matter how fast your ISP advertises you connection as being, latency can still cause major delays. Naturally, when you’re delivering video, that’s a big deal. If it takes a second or more to make a request and receive a response, the likelihood is that your viewers aren’t having a great experience.

Latency can lead to playback delays, particularly when viewing HD content. In China, the internet is pretty heavily regulated. As a result, many companies lack infrastructure on the Chinese mainland. Also, many western websites are blocked outright. By using a CDN POP in China, vzaar can ensure that latency is much lower than other video hosts. We can also guarantee your videos will be playable and not blocked by the Great Firewall.

How do I get access to it?

All of our current plans have some In-China Playback included in their standard packages. With the Launch plan, only 25GB of the 1000GB bandwidth allowance can be used, whilst the Scale customers (and above) can choose to allocate their entire bandwidth allowance to In-China Playback if they wish.

Once your subscription is set up, you'll need to head into your account’s delivery settings and enable “Premium POPs” under the “Region Settings” section.

How much can I deliver?

With the Scale plan, you could choose to use the entire allocated 4TB bandwidth in China. If you have a mix of China and non-China playback, you just need to be within your package limit. For example, 2TB in China 2TB non-China.

With the Launch plan, 25GB out of the 1000GB can be used in China. So if you are just launching into this region and need to test, this should be enough for you. If you find your audience in China is really taking off, we do suggest the Scale plan.
