When lightning hits the energy goes down anything that conducts - and leaps some gaps that don't (obviously). Unplug your gear, or if you can't get some VDR's / Gas Discharge Tubes (Yes I know you're not supposed to use them on mains) / AC-DC-AC power converters in the likely paths. There are some people out there who are going to blame you (otherwise) when this idea doesn't work.
