According to wikipedia[1] they incubated it, and it has since been run and maintained elsewhere. Same deal with cloud.gov (though that was an 18f prototype)
In fact it looks like most of their projects were prototypes, incubations or partnerships with other agencies and departments. Seems like a modern digital agency / consultancy within the govt. I'm not sticking up for the decision to cut them (I think it's a great agency that clearly bore fruit), but this is HN and we should have our facts straight.
