EVE Online Singularity test. What's Singularity? It's the New Eden equivalent of a test server, and you can connect to it by following the steps for the SisiLauncher tool on the EVE website.
This week's test starts tomorrow at 3:00 p.m. Eastern and will last about an hour. CCP says you'll be testing "performance improvements to the overview window and other parts of the UI," and your character will receive two million skillpoints to distribute as you see fit.
Further info is available on the (new and improved) EVE web portal.
