The Cardiff Internet Exchange was formally opened in October 2014 and is located on the 14th floor of the BT Stadium House, in the heart of Cardiff's Central Enterprise Zone.
The majority of the “major intersections” of the Internet in the UK– called Internet Exchanges – are located within London. There are a small number outside, but none in Wales or the South West in general. So, for example, if someone in Cardiff is using the Internet to communicate with someone else in Cardiff, it is the norm for the data to go Cardiff-London-Cardiff due to the lack of local interchanges. Most communication outside the UK follows a similar route, leading to delay and resilience issues (latency). Importantly, this also increases costs for local communications businesses and Internet Service Providers (ISPs).
This new development in Cardiff will help overcome these drawbacks.
