The following shows the current status across participating servers, broken out by region and server.
If any particular server has data that is outdated by at least 10 minutes, there will be a warning icon to designate it as such.
The auto update switch allows you to toggle server data being updated automatically or not. If it is enabled, server data will be fetched approximately every 15 seconds. This requires Javascript, and your browser must also support using EventSources.
The alerts manager (button next to the help button) allows you to set up notification alerts for specified criteria (e.g. certain region, game modes, minimum players, etc). If the criteria is met, you will receive a notification about it. This requires Javascript, and your browser must also support using Notifications. Additionally, this will only work if you have this page open and auto update enabled. When you attempt to add a new alert, you will be prompted to allow the website to send you notifications. If you deny this, you will not be able to add any alerts. If you denied it by mistake, you can just try to add the alert again and it will prompt you once more.
