We are running about 50 development servers for the Storage Systems 
Research Center in the University of California, Santa Cruz. All Fedora. 
We will be updating all machines to F29 as soon as it is released. The 
reason is that we want the students to have access to the latest 
development toolchain, libraries, and other tools from the Linux world 
in a reasonably stable fashion. Fedora is the best fit. Not bleeding 
edge, but not outdated either. Our infrastructure servers, such as file 
sharing, cluster management, etc., are all Fedora machines too, for 
homogeneity and simplicity.

We don't need 24/7/365 uptime, but in my memory, there has been no 
downtime caused by anything in Fedora in the past decade. And we always 
do in-place upgrading when a new Fedora comes out. Upgrading from one 
Fedora to the next never failed us in the past decade either in my memory.

Occasionally, one or more machines will be loaded with CentOS 7 for a 
few months for running Lustre or some other CentOS/RHEL certified software.

This is unrelated to the campus-wise Linux clusters that are managed by 
the university IT department, which maintains hundreds of CentOS 
machines for the whole campus.

I also know colleagues who maintain Fedora as servers from my other 
jobs. These were for all kinds of services: email, file storage, 
development, etc. Why Fedora over CentOS? I guess Fedora is more fun to 
play with and is stable enough for these applications. As I said before, 
in-place upgrading for Fedora is pretty reliable. And doing it once a 
year (or every 6 months) to get the latest software is a good bargain 
for a techie.
