CPU is the type of upgrade.

EUA is the system that processes the upgrades.

EUA is what's broken.

At 96 hours, the EUA should have swept the flight and allocated something. The fact that the flight has remained F9 R9 well beyond that is suspect.

As I do with all such EUA anomalies, I call in and request a manual upgrade or a bug report be written. I usually end up with the latter.
