Thanks Scott. That clears that up then! It must be a difficult thing to figure out - how much grunt to give a site like that - where you have no benchmark to start from. Somewhere along the line you have to decide how many simultaneous sessions to cater for, and in the case of Jetstar, it must have been a total guess. They'd have known the publicity and the $29 fares would have generated a lot of traffic, but how much? Putting a number on it must have been tricky, and judging by the results, not an exact science.
Then again, it could be a fair decision to make that there will be a big peak at the launch, which will settle down to a lower level later. So to engineer the servers for the large launch traffic at the start, and then be saddled with the costs of all that grunt that will never be used again would generate debate in the launch planning I'd have thought.

Does anyone have any input for that? The decisions were made at a sleazy hooters bar one night after a few too many drinks. The way they worked out the load was, to take a packet of tooth picks, throw them in the air, and the ones that land on the table, was the expected total number of hits likely to visit the site. They then outlined a prison break style mud-map on a cocktail napkin, followed by some outlandish purchasing from Dell online.
