Spampanato; the broadcaster realized the first Italian webcast system making freely available the sessions of all the Italian Parliament's broadcast and archived sessions. The website of Radio Radicale made possible the streaming of the sessions held by the European Parliament, Court of Audit, High Council of the Judiciary and other institutions. Computer technologies The website is made using mainly free software like Linux, PHP, Apache HTTP Server, Apache Solr, MariaDB, Varnish, Nginx and Icecast. It is managed with the open source CMS Drupal, published under GNU GPL licence. All the hardware units of the content archive and distribution system are allocated in Roma into two different server farms located in the headquarter of Centro di Produzione Spa. The first server farm holds the racks of the SAN storages with mp3/mp4 files and online distribution systems of audio and video streaming (Icecast and Wowza respectively), set up on Dell servers with the Linux OS Slackware. The SAN is formed by EMC, Dell and Qnap storages with RAID5 discs interconnected with the iSCSI technology for a total space of 170 TByte. The second server farm is mainly dedicated to the interconnection of network devices and the supply of web services through firewall, switches and routers made by Cisco. Both server farms have UPSs, generators sets and air conditioning systems to guarantee the management of the operative continuity at a steady temperature and humidity. All the hardware is redundant to guarantee optimal levels of fault tolerance eliminating the main single points of failure. The internet connection happens with two fluxes on optic fibre of 1,000 Mbit/s each from two different ISP with that Centro di Produzione Spa has autonomous system relations. To prevent control and managing activities of the computer network, Centro di Produzione Spa uses software like Nagios and Netflow which can promptly report every possible logical or functional anomaly of the services supplied. In December 2015 the experimentation for the transition to IPv6 begun through the address assigned to Centro di Produzione by RIPE NCC. Since February 2016 the website is available in dual-stack IPv4+IPv6 with the HTTP/2 protocol. Since 2016, Radio Radicale has used a content delivery network developed by Google through the Project Shield technology, an initiative by Google Ideas (now Jigsaw) intended to prevent possible Ddos attacks.
