Actually....

I have seen some colo ISP's that put every customer in a separate
VLAN.  Typically they feed these two two routers, running VRRP or
HSRP.  So a single server needs a subnet with space for 4 devices,
router1, router2, virtual gateway, and server IP address.  The
smallest subnet that can do that is a /29.

So, it is possible for a single colocated server to consume a /29.
Not everyone does it that way, of course.
