Does the Pauli exclusion principle instantaneously affect distant electrons?
If this rule works, could you not set up an experiment to test the theory (as described by Brian Cox in his A Night with the Stars lecture$^1$) and monitor another piece of diamond to see if the electrons change levels in time with the changes in energy of the electrons in the heated piece? If you used a pin point heating element that could change temperature at different frequencies, would you detect the frequency change in the monitored piece?
