I work in IT and in today's world some of the IT issues Disney has are laughable though. 10 years ago it wouldn't have been, but issues like your website going belly up due to too much web traffic, there are easy solutions to that problem today with cloud. E-commerce companies like Amazon handle just as much traffic on a regular basis with no issues.
Exactly even our own government agencies here in Washington State have figured that out. WSDOT knows that when there is a big snowstorm in Seattle the web traffic to the road conditions web page soars by 1000% or more. To handle the traffic they just use Amazon's servers.
