Central UPS 70NET 40/33

A new central UPS providing higher protection of client devices against power failure was installed in the premises of COOLHOUSING.NET data center. It is a modern UPS with excellent input parameters without the necessity of complementing additional filters, multi-pulse rectifiers, etc. UPS 70NET series works on an on-line basis with dual voltage conversion. Controlling of the power supply and parallel cooperation is based on DSP (Digital Signal Processor). This revolutionary principle ensures very fast response to any load requirements and requirements of the UPS itself. It optimizes battery charging and ensures uniform load of parallel-connected UPSs.

Computer infiltration means unauthorised entering programme code into computer system in order to perform undesired (often concealed) activities.

What is a AWstats?

AWStats is a freeware tool generating advanced web, stream, ftp and email statistics into a graphic environment. This server log analyser works as CGI from the command line and displays all available information contained in logs on several graphic websites. Since AWStats often uses small parts of information files at a time, there is no problem processing large log files which also affects the speed. It is capable of analysing log files from all major server applications, e.g. Apache log (NCSA combined/XLF/ELF log format or common/CLF log format), WebStar, IIS (W3C log format) and many other web, proxy, wap, stream, mail and some ftp servers.
