Calculate monthly bandwidth from traffic volume and average page weight.
Caching removes most repeat asset transfers, so effective bandwidth is well below the naive product of pageviews and page weight. Peak days can run at twice the average, which is what matters for burst limits. Bandwidth overage charges are usually far more expensive than the base plan, making headroom worth paying for.
