What happened to Domainbigdata.com?

[Namefy.com]

I was using domainbigdata.com almost daily to skip trace hard to find domain owners.. Anyone know of a free alternative to this site? It seems it just went down one day and hasn't returned in months.. :/

I don't have an alternative, just wanted to say, big mistake they made it free. It's expensive to run something like that that.
