Later in 2006 Telecity Group plc bought the European assets of the US-based Globix Corporation.
Following a rebranding exercise implemented in August 2007, TeleCity, Redbus and Globix (UK) began to trade under the name TelecityGroup. In October Telecity Group plc listed on the main market of the London Stock Exchange  and in December TelecityGroup were admitted to the FTSE 250 index.
