FWIW, I asked on reddit, and the universal response was that atmospheric drag really can slow it down that much.

Rumblings that the payload for the Zuma mission did not achieve orbit. Possibly disinformation, of course.

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. |

The picture is interesting, I get the two lines where the first stage did it's burns, and the gap seen in the arc between MECO and the second stage starting up, the up-loop showing the back-burn of the first stage, but I don't get why the first burn of the first stage's reentry burn appears higher than where the first and second stages separated.
Just angles? |

Welp, this doesn't sound good.
Highly classified US spy satellite appears to be a total loss after SpaceX launch |

For what it's worth, here's Gwynne's official statement about Zuma:

So good news: no delays to FH or the rest of SpaceX's manifest. Bad news: the U.S. appears to have lost a very expensive satellite. |
