Unshared, ultrafast Internet connectivity

Uncontended DarkLight

Getting exactly what's advertised

One of the most common issues that people experience with their Internet connectivity is the fact that they don't receive the speeds that are promised in adverts, particularly at peak times. In most cases, this is a result of overly contended services and insufficient network provisioning.

Essentially, most Internet services are shared by multiple premises. This isn't necessarily a problem if enough bandwidth is allocated to meet demand (as we do with our ADSL services) - but many ISPs don't do this, leading to underperforming connections, particularly when multiple users simultaneously attempt to use high amounts of bandwidth.

DarkLight is absolutely uncontended from us to you. It's provided directly to your premises and not shared with any others, making for a completely uncontended, non-GPON service. That means that you'll always get the speeds that we advertise, and ensures that you don't have to deal with slower connectivity when you need it most.
