Diablo 3 Server Checker is a utility that shows if servers in Diablo III are online.
The app can also be attached as a home screen widget so that you can always know if your particular server is online. Diablo 3 Server Checker is a simple app that relies on Blizzard’s server status page to display the data.
It may be common that Diablo 3 Server Checker shows the server is online when the server is offline, but that is due to Blizzard not updating their website. Diablo 3 Server Checker will check servers in the United States, Europe, and Asia. It will also aggregate the server status threads, informing you of scheduled maintenance or other issues reported by Blizzard.
If you are a constant Diablo III player, Diablo 3 Server Checker is a great tool to keep you informed.
