Curiously how many of you who runs vps/dedicated server use what kind of server os? me i use centos 5.
CloudLinux for all shared servers. Most VPS with CentOs 5.6 and Ubuntu 10.04. Dedis usually run CentOs 5.5/5.6 or Windows Server 2008 Web edition. Also some servers are running on Fedora and OPenSUSE.
hosting = CentOS 5.5/5.6 local testing = CentOS 5.5/5.6/6.0 and Debian 6.0 (later will try ubuntu and freebsd)
