While Cruising at FL 370 we received the following lights: Windshear; Speed Brakes; GRD PROX (GS INHB);only the right bulb of Pull Up; Cabin Alt; Master Caution (EICAS; ATC Fault). At the same time the Captains altimeter spun continuously; First Officer (FO) airspeed went to zero. The autopilot did not disconnect. There were no tones or audible warnings.  The QRH was referenced. About a minute later everything returned to normal with the exception of the FO altimeter. It remained failed for the remainder of the flight.  It was determined that we needed to descend from RVSM airspace after conferring with dispatch and maintenance.  It was determined by maintenance that the best course of action was a divert into ZZZ. After a discussion with the Captain of the risk factors of going into a Special Use Airport; we both agreed that it was safe to do so. The flight concluded without further incident.  I will add that neither the Captain or I are certain that weather and NOTAMS were sent to the ACARS.
The B767 pilot received several apparently spurious warnings which also affected some of the flight instruments. Everything returned to normal after about a minute except for the failure of the First Officer's altimeter. The aircraft was diverted to a maintenance base.
