solar flares can cause problems with network hardware

Did you have a network hardware failure, the night of August 3, 2010? If so, the cause may be due to a solar storm that hit the Earth directly as widely reported in the news.

NASA astronomers reported that on 1 August, there was a huge eruption on the sun that are positively charged plasma ejected from the surface immediately directed towards the Earth. These charged particles entered the Earth's atmosphere after a few days and clashed with oxygen and nitrogenmolecules to create what is known as cosmic rays.

In general, the Earth's atmosphere is a good job of deflecting cosmic rays in the upper atmosphere. That's why the discussion of electronic failures caused by solar flares or cosmic rays is often limited to satellites in orbit. The satellites are much more likely to be affected by the radiation, being higher in the atmosphere.

When solar flares are larger than normal but cosmic rays cantouched the surface. Generally, the material for the North and South poles, the more likely to be affected by radiation.

I worked for a company in Chicago a few years ago when we had two distinct forms Supervisor Cisco Catalyst 6500 Series switches to die the same night. The hardware can be found in two different locations with very different power sources. Knowing the failure rate of this equipment, with two errors in one night is very rare.After a lengthy investigation by Cisco's Technical Assistance Team has been established that the errors were due to a solar flare that hit like our site with cosmic rays. At that time, I do not think their explanation, but looking back now, you can. In fact, Cisco has documented the cosmic radiation as a cause of hardware failure. Network equipment such as high-end switches are more susceptible to cosmic radiation than other electronic equipment due tosensitive electronics packages for moving at high speed.

So the next time you see news for the solar flares on the ground, keeping an eye on any hardware problems occur on the network running.
