Regions

Photon Cloud provides you with global connectivity to allow low latency gaming all around the world.

Setup Regions In PUN

ConnectToBestCloudServer(string gameVersion) connects your client to the Master Server with the lowest ping. Results from pinging all Photon Cloud Master servers are saved in PlayerPrefs.

Use OverrideBestCloudServer(CloudRegionCode region) to explicitly set another region as "best" one.

You can setup the region as part of editing the PhotonServerSettings asset. Connecting to a region then becomes as easy as calling PhotonNetwork.ConnectUsingSettings().

For additional setup info using PUN please refer to the Initial Setup doc.

Available Regions

Photon Cloud has servers in several regions, distributed across multiple hosting centers over the world.

Each Photon Cloud region is identified by a "region token". To pass the region token with the "Connect" method of your client, call PhotonNetwork.ConnectToRegionMaster(regionCode, gameVersion).

Dashboard Regions Filtering

You can filter the list of available Photon Cloud regions per application on the fly directly from the dashboard.

Photon Cloud: Regions Whitelist
Filter Photon Cloud Regions

Go to the dashboard and then click "Manage" for a chosen application and then click "Edit". You will find an input field where you can enter the list of whitelisted regions as follows:

  • the allowed list should be a string of region tokens seprated by semicolon. e.g. "eu;us".
  • region tokens are case insensitive and are defined here.
  • undefined or unrecognized region tokens will be ignored from the list.
  • empty ("") or malformed string (e.g. ";;;") means empty list.
  • empty list means all available regions are allowed.

Once you confirm and save, the operation GetRegions will return only the filtered list of regions. Thus clients should select from that list but it's fully possible clients connect to any available region explicitly. Take into consideration that dashboard updates propagation can take up to 10 minutes.

Using The Chinese Mainland Region

First, you need to request access to the Chinese Mainland region for your Photon app. Send us an email so we could unlock it for your AppID.

The Photon NameServer has to be local to China, as the firewall might block the traffic otherwise. The Chinese Photon NameSever is "ns-cn.exitgames.com".

Connecting with clients from outside of China mainland will most likely not produce good results. Also, connecting from the Photon servers to servers outside of China mainland (e.g. for Custom Authentication, WebHooks, WebRPCs) might not be reliable.

Important: in the current phase, changes you make to your app via your dashboard are not automatically reflected in app caches for China. Let us know by e-mail, if you have an update request there.

Also for legal reasons, you need a separate build for China and we recommend to use a separate AppId with it. For example, use a compile condition (of your choice) to change the AppId and the Photon NameServer depending on the build.

Follow these instructions to make a special build for the Chinese market:

  1. Set the AppId to the application that has China region unlocked. If you want to use same project and have different builds you can do something like this:
  2. Open the "NetworkingPeer.cs" file and set the NameServerHost to "ns-cn.exitgames.com":
  3. Update CloudRegionCode and CloudRegionFlag enums to add new "CN" (or "cn") region token as follows:
  4. Use PhotonNetwork.ConnectToRegion(CloudRegionCode.cn, gameVersion) to connect to Chinese Mainland region.
