Unless explicitly advised otherwise I would expect allowances to apply to the account as a whole.

Unlimited? Despite having failed a maths degree I know that nobody can have infinite storage or bandwidth. They just expect that with a large customer base the usage will simply average out. When something new comes along that has everybody requiring more capacity at the same time they will start screaming about "fair use".
