Krzysztof of Universe@home canceled a lot of faulty tasks today, server-side.
But not just ULX tasks, also very many BH2spin tasks.
If you happen to have a bunch of Universe@home tasks on your computers (regardless if downloaded but not yet started, or already finished successfully but not yet uploaded), then [Update] the project (regardless if you have network transfers enabled or suspended right now).
The client will then get notified by the server which of your precious tasks have lost the admin's blessing and are already in "canceled by server" state.
--------
Edit, now the server no longer responds to scheduler requests or file transfers. The web site and forum are still up though.
Edit 2, scheduler and transfers work, but highly unreliable with frequent timeouts.
