This is the testing instance of LCZero server.
Here we pretend to test things but sometimes actually run things to completion.
As our previous 'run to completion' has not made much progress recently, main page and default contributions have been reset to our new actually testing run while we wait for lc0 0.20.0 to be prepared with a new network architecture for our next main run.
You can get the client and lc0 releases from those links.
