Operating System and Software

All new user servers at pair Networks run the FreeBSD or Ubuntu operating system (FreeBSD & Ubuntu ).

UNIX operating systems have been proven stable and reliable through decades of enhancement and improvement. pair Networks uses the open-source FreeBSD and Ubuntu operating systems exclusively for all of our Web hosting services. You can count on this added reliability, scalability, and security as a benefit to your site.

On the FreeBSD and Ubuntu sites, you can read more about the past, present, and future of these operating systems.
