History
RETN originated in 2002 as a joint project of Saint Petersburg operators PeterStar and Eltel to connect the Russian internet to Western Europe. A point of presence was opened in Helsinki in 2003. The first RETN Ltd was incorporated in London, UK.
In 2008, RETN announced a pan-European ring connecting Russia to Europe via Scandinavia and Ukraine; at the beginning of 2008, RETN leased fiber from the Helsinki-FI/RU border and launched its own DWDM communication line from Helsinki to St. Petersburg, providing the first redundant connection between European Russia and major European internet exchanges (IXP). Internet traffic on the RETN network grew exponentially. This served as the basis for a much more ambitious project – the construction of a Pan-European ring network: Stockholm – Helsinki – St. Petersburg – Moscow – Kyiv – Budapest – Vienna – Frankfurt – Amsterdam – Hamburg – Copenhagen – Stockholm and Amsterdam – London – Paris – Frankfurt (over 10,000 km), which RETN implemented in 2009–2011.
In January 2021, O'Sullivan succeeded Samarin as CEO; Samarin first remained as Chairman and then recently transitioned to Chief Technology Officer.
