Is that an Atlas problem, or a Centaur problem?

Since the two stages are necessarily an inseparable launch
system, it's an Atlas problem, in the second stage.

I disagree, since the same stage has been used on other launchers.

Yes, but this still a system since Atlas V currently has no
other upper stage. It succeeds or fails as a system.

Still disagree. The Atlas has something called the Centaur as a
payload (which in turn had the satellites as a payload). The Atlas
succeeded in delivering the Centaur to its engine ignition point, per
spec. It was a Centaur failure, not an Atlas failure. After all, if
the Atlas is used to deliver crew module to a Bigelow facility, it's
not obvious that it will use a Centaur to do it. Similarly, if NASA
comes to its senses and gives up on the Stick, they might go with an
Atlas, but use a different upper stage (perhaps similar to the current
one planned for Ares, with the J-2 derivative).

You're behind the times, Rand. The "Atlas V" is a family of launch
vehicles, composed of the "Common Core Booster(tm)" and the "Centaur"
upper stage. There were also a bunch of ICBMs and booster stages
known as "Atlas", but those no longer exist.
