The steel superstructure would be only a partial shield.  Also, the most
likely mechanism for trouble from a pulsed magnetic field would be induction
(voltage pulses, such as those which would be induced in signal lines), so
a volume larger than the building itself might have to be considered.
Good gear should have a high tolerance for such common-mode interference,
however.

Well, how about....   swapping in a better box for a week and seeing whether
or not the failures continue?
