We’re really excited to announce we’ve added a new Pusher Channels cluster in Sydney! This new cluster, called ap4, not only allows you to achieve lower latencies within the Asia-Pacific region but makes it easier to comply with local regulations concerning the Personal Identifiable Information (PII) in the state of Australia.

To use the Sydney (ap4) cluster you need to select it when you create a new Pusher Channels app. Here’s where you choose a cluster when you create a new app:

Then, in your Channels clients, specify ap4 for APP_CLUSTER to use this cluster. Here’s an example in pusher-js:
var pusher = new Pusher(YOUR_APP_KEY, { cluster: “ap4” });

You can find client-side examples as well as backend examples on the Cluster Configuration documentation page. All of the official Channels libraries support specifying a cluster.

If you have an existing Channels app, you cannot edit its cluster. If you want to change the cluster for an app in production, you should follow the steps to migrate it to a new app to ensure that your users don’t experience service disruption.

What other regions should we have the clusters in? Please let us know by emailing feedback@pusher.com or tweeting @pusher. For larger customers, we are able to deploy dedicated clusters to any region, you can contact sales to learn more.
