For further information, you can visit the #wikipedia channel on the Freenode IRC network.

Wikipedia is now one of the most visited sites on the Internet by traffic and continues to grow, and as a result the Wikimedia Foundation has a constant need to purchase new hardware. If you would like to help, please donate.
I bet they will get high $xx,xxx in donations from the downtime.
