If your website is based at the Microsoft tools (Access, SQL, ASP, FrontPage, Visual InterDev, Microsoft Office Extensions, Microsoft Office 2000 Collaboration, Access databases or MSSQL databases) then UkrainianHosting.com recommends to use Windows 2000 Server for website hosting.
For Perl, PHP, MySQL, Apache, GNU C/C++ users UkrainianHosting.com recommends to use Unix Server with OS FreeBSD which is LiNUX compatible.
