What Happened To / Where Is The Site That Had Huge Amounts Of Free Data For Projects?

Hi. I don’t remember the name of the site, but there was a site that had tons of tables of varying data for use in projects. I believe it was free and/or open source. If I remember correctly, it was called something like “opendata”. It’s been a few years since I’ve seen it so it might have disappeared, but I was hoping someone remembers and can point me in the right direction.

Thanks!
