how about this? what if webservers had one section of servers for the northern hemisphere and another for the southern hemisphere and both would be at full power during the day but during the night they could shut down a few servers to save energy. would this even work or save any energy?
What about people who want to access websites at night? Would you be happy if Mac Rumours was not available all the time? What about other websites.
Servers need to be on 24/7.
