Does anyone know of a website kept up to date?

Most people will tell you vpfree2.com. To which a lot of people will say that it's woefully out of date, incomplete and full of errors. And to an extent that's true. Still, it's the best source I am aware of. Except if you have specific games and venues, then I think it's better to inquire here!
