I got terrible headache today because of 2 web servers i managed downed due to gateway error in the data centre. IIt is quite depressing since you could not do anything and waited. I smoked a lot today.
The internet is not one straight line. Your computer –> Server. Not that way. In order to view one web site, you have to go thru coppers, wires, cables, under sea cables etc, but for laymen, they just want it to work. Switch go berserk sometimes. Machines are and computers are not reliable anyway. Plus if you have moving parts. They will break down one day. You just have to be prepared.
