Minimize demand peaks

Web traffic in schools is characterised by enormous but short-lived spikes in demand at the start of lessons, as whole classrooms access resources. Schools often measure their bandwidth capacity needs according to these peaks, despite average demand during the rest of the day being 6 or 7 times lower. Thankfully, these peaks are highly cacheable, and repeat requests can be served to multiple users locally. This is more cost-effective than paying for internet capacity that will be underutilized outside of peak times.
