Several times over the last few years I've seen WP outages which turned 
out to be bad config pushed in to production and then quickly reverted.  A 
few were patches to the Mediawiki software, for example.

I guess they don't have a preprod/UAT environment :)  While I can 
understand them being able to simulate the scale, a small UAT environment 
to test config rationality wouldn't go astray.

I hear Wikipedia has a monitoring system.  It involves alerts issued by 
millions of people around the world :)

Cheers,

Rob
