I dont have the reference to hand but with Cisco the crash reason hinted at something very odd which was either a hardware failure or cosmic ray - i think it was a parity error or something similar. I remember this because I had such a reload and it was during a period of heavy cosmic activity.. as the hardware had always been reliable and was reliable after this was beleived to be the cause Steve On Thu, Apr 19, 2007 at 10:17:49AM -0400, Robert E.

With certain susceptible Sun CPUs which were popular during the last sunspot maxima, this was actually demonstrably true (and acknowledged by Sun), so don't laugh too hard.

Around that time there was quite a bit sunspot activity and the moon had an unusual position too. The NOC contacts of your ISP's probably may be of more specific help. But make sure to ask them for their networks SPF (sunspot protection factor). That's an important metric to qualify their network reliability.
Are you sure it was sunspots? My NOC contacts were seeing substantial memory corruption due to cosmic rays.
