What happen to Wikipedia today ?
It is reported that Wikipedia is down due to a power failure in the data centre. This has triggered a backup of 170 GB database on several servers and running recovery.
I can imagine that the same kind of situation will probably not be experienced by CNN, Google or Yahoo. To avoid a single point of failure paralyzing the whole operation, I don't quite understand why Wikipedia does not deploy site diversity in its network configuration. Time has come for Wikipedia to re-consider a more robust setup !!
