  • Alexey Kashyn , Director

    We are Ukraine’s first television network company producing and broadcasting 3D content. Until now, dealing with few Data Centers but could not find the proper level of service and reliability. We felt the difference after placing our equipment in Cosmonova DC, that provided high-quality Internet links and networking, which is very important to our target audience. This is a valuable criterion for us as we work mostly deal with bandwidth-consuming HD video content.

    Also such a collocation was really suitable for us as there are direct communication links to most of operators and now it`s easy to transfer not only unicast but multicast traffic which requires QoS network.

    We noticed also the competence of operation personnel of Cosmonova. They are skilled enough to make on-site maintenance and monitoring of our video specific equipment.

    The Sonar company is one of the leading content distributors in the Ukrainian subscription based and terrestrial TV market, and has been working with Cosmonova for more than five years. During this period, we have seen numerous proofs of the Cosmonova team’s expertise. Thanks to the TV platform and an expert team, TV carriers who are unable to receive our satellite channels, can get them over IP. We are more than willing to recommend the Cosmonova company as a reliable technical contractor, since an increase in the carrier’s channel list means an increase of the carriers’ attractiveness to potential customers. And especially, the top-rated and quality channels offered by the Sonar company. If a carrier cannot receive our channels from the satellite, we recommend you contact the Cosmonova company and get our channels over IP.

  • Sergiy Tsviliy, IT Manager

    The initial contact between us was established at the beginning of 2013. The company introduced itself as Cosmonova and offered their services of providing Internet access. We have thought over the offer for a long time since there had been substantial difficulties in the laying of optical fiber in the territory of the Academy and we did not wish to waste time on it. We agreed that we would keep in touch every 3-5 months. In 2015, our then provider began to fail in its work and we remembered of the provider who was so eager to connect us. We got in touch with them, agreed on the rates and time terms of the work, and had no problems regarding the connection or signing the contract. We are grateful for the high quality services we receive and we have been with Cosmonova ever since.

    National Television Company of Ukraine (NTCU) would like to express its sincere gratitude to LLC Cosmonova for the prompt and quality services of the online broadcast of the Eurovision-2016 final and organizing the online broadcasting of the XXXI Summer Olympic Games in Rio de Janeiro on the UA: Pershyi (UA: First) website for Ukraine.

Thanks to services provided by Cosmonova the success and victory of Ukrainian singer Jamala had been watched by over one million visitors of our site. The NTCU decided to entrust the internet broadcast of such an important event as the XXXI Summer Olympic Games in Rio 2016 to Cosmonova. To ensure the highest image quality Cosmonova’s professionals organized reception of the terrestrial signal in sdi, and provided backup reception via Internet using the rtmp protocol. Transcoding of the studio signal into the required formats with various bitrates was organized on the Cosmonova platform for TV signal processing, and a player with signal bitrate adaptation depending on the Internet connection speed of multiple users with selection of the highest possible bitrate was prepared for the UA: Pershyi website. We hope that owing to the Internet broadcast organized by Cosmonova even more Ukrainian citizens will watch this grand sporting event and support our athletes. We express our utmost gratitude for the company’s professional approach and look forward to fruitful cooperation in the future.

  • Roman Motrenko, IT Supervisor

    Throughout our cooperation with Cosmonova we have used a wide range of the company’s services. We were provided communication between the company's points of presence and Internet access. We also placed our own equipment in the Cosmonova Data Center and leased dedicated virtual servers. Cosmonova was originally selected as a company that could provide communication channels wherever necessary, including points in the Kyiv region and the Data Center of another provider. At the same time, the price policy was absolutely acceptable without far-fetched non-sense such as "this is outside Kyiv so it will cost more", which was common among other providers at the time. The company's employees proved to be professionals, who, first of all, constantly strive to improve the quality of services provided, secondly, are always ready to promptly react to technical and business inquiries, and thirdly, are open and honest in communication. We are extremely happy with our ongoing cooperation. We are pleased with the high responsiveness and flexibility of Cosmonova, the wide range of the services it offers, profound fairness to customers, and the price/quality ratio of the services. I would also like to note the shortest possible response time to incidents and a minimum of bureaucracy in resolving issues, which is crucial in ensuring high availability of IT services for businesses.
