Are Internet News Sites Ready for Major World News?

An anonymous reader asks: "Heading says it all really - are Internet news websites ready for the next big world event? news.bbc.co.uk already switches format under heavy load (not sure if this is automatic or not) and i'm sure some other sites do the same. But should a major world event take place in the coming months/years, the Internet is going to be the primary news source for many millions of people, particularly those without access to a quality television news service. How will / can it cope?"
