"CSG managed the grant for the leased line and the installation went very smoothly. CSG then came to our offices to train our staff on the new phones, which was really helpful. CSG also listened to what our staff needed and reprogrammed the system to meet their needs.It is probably the single best thing that we have done over the past few years to be honest. We were apprehensive at first as we thought it sounded too good to be true, but since the leased line has been implemented our internet has been superfast and we have had no problem with calls dropping."

James Porch, Dale Building Maintenance Ltd

What is "peering"?

Peering is the process by which two or more internet service provider networks connect via an Internet Exchange (IX) to send information directly. 

What will peering do for my business?

  • Businesses currently communicate via the one route, Cardiff - London - Cardiff due to the current lack of local exchanges but with the new IXCardiff, these issues will be no more.
  • Connecting to the internet exchange avoids third party costs, which means lower costs passed on to you, the end user.
  • By keeping local internet traffic on local infrastructure increases efficiency and time awareness.
  • Transferring data to your customers, staff and business partners will be quicker and easier.
  • Connecting to the internet exchange will create business growth in the digital world across all sectors and geographical areas.
