What options are available, if you want to provide magnetic shielding as
well as electrostatic shielding?

If the room is underground, would that help much?

I think it's a bit odd that electrostatic shielding of the room would help
so much, if the equipment inside the room is built with good shielding to
begin with. Maybe that was the problem--the gear inside the room wasn't
really designed with excellent shielding?
