GNUtransfer - GNU Hosting, Mar del Plata, Argentina
We provide virtual servers and web hosting services since 2005 using Debian GNU/Linux as main operative system.
We own six powerful servers running the Xen hypervisor on Debian stable to support our VPS offer. Our shared hosting platform is also based on Debian as OS and many of the best free software pieces: Postfix, MySQL, PostgreSQL, Apache, proFTPD, PowerDNS.
The reason to use Debian is the fantastic quality it has in terms of performance, stability, package management system and services administration. We love the project and its philosophy.
