It's definitely weird. The only official statement is that the F9 performed its duties fine. The payload is classified, so who knows if it ended up having an issue of its own or if it was some sort of test that didn't really require a true orbit. Or maybe it's up there just fine, and all of this secrecy is just to further conceal the mission's purpose.
I doubt we'll ever know, but it doesn't seem like SpaceX is reacting like anything went wrong at all. FH is rolling out for what is expected to be a Wednesday static fire, and there haven't been any rumblings at all about any other launches being delayed due to a failure.
In the meantime, this shot from the launch is really cool.
