Cutting down the cost of speeding up

It's difficult to overestimate how big an effect Internet connectivity can have for businesses and schools. It's estimated that the average UK worker loses a full 38 hours of productivity a year due to slow or unreliable connectivity, while learners and teachers in schools with slow connections can find themselves unable to access useful resources - a major issue for education.

DarkLight was designed to deliver ultrafast connectivity to our customers at a cost that's typically significantly lower than comparable leased line solutions, making sure that more organisations than ever can see the incredible benefits that come with introducing ultrafast connectivity.

With symmetrical performance ensuring that upload speeds are just as fast as downloads, DarkLight is ultrafast on every level, with connections starting out at 300 Mbps. We offer a range of speed options, with our options including powerful gigabit connectivity and a truly world-class performance level - 10 Gbps!
