I know, but it is impressive that they are doing it for $400.
A raspberry PI could handle the compute.
I don't think they are overpaying for what they are getting. $400 is not a lot for a proper site that serves a lot of bytes. I just don't think it's that impressive either -- it's just yet another website serving static assets through a CDN, with low QPS too, so I don't see why it's noteworthy.
