Are you sure? My state is that e.g. Netflix, Google, Akamai?, etc. offer ISPs to put a (couple of) 2-4U box(es) inside their network, for free, only requiring power and cooling (and networking). The ISP wants this, because he'd otherwise get the traffic dumped into his network at the edge, i.e. an internet exchange/carrier-neutral DC. That costs the Provider significant routing and intermediate-distance (40~100km, i.e. CWDM long-range transceivers) bandwidth. This is much more expensive then feeding the google box with power.
