I hadn't really thought about it much, but googling it looks like there's a discount programme for a committed spend of around $1M/year. For a small company, that's a lot of money, and it was an unusually large amount of bandwidth for the size of company. I suppose it makes sense now I know they're interested in companies spending that sort of money.
