NetBSD Use Case in a Large-Scale UK Network
This 2005 message describes a UK network administrator's experience running NetBSD 2.0.2 on 29 servers supporting more than 4,800 users. The systems handled MySQL, Apache, Postfix, Samba, and NFS-connected file services, and the author contrasted the stability of NetBSD with prior Windows-based operations. The item is primarily a user testimonial about operational reliability rather than a product announcement.
