General questions

How does my connection work?
We provide your internet connection through a cable we rent from a network owner in your area. The network owner can be TDC, Norlys, EWII Fibernet, Nord Energi Fibernet or OneFiber.

From the network owner's network, we route traffic via our transport network to our data centers in Tåstrup west of Copenhagen. Here we exchange traffic with the rest of the Internet via NL-ix, Netnod and GlobalConnect.
Peering and uplinks
If you want to see which way the traffic takes out of our network, you can take a look at our looking glass .

You can also take a look at our profile at PeeringDB .
We monitor the stability of our network by pinging all customers' equipment every 5 minutes. Malfunctions are automatically detected on our status page .
The highest speed is achieved on fiber - all fiber customers can get 1000/1000 Mbit/s. On coax we have speeds from 200 to 1000 Mbit/s, while on DSL we can deliver speeds up to 100 Mbit/s - in some places up to 300 Mbit / s.

You can see how to test the speed of your connection here .
Bandwidth-delay product
The speed of a TCP connection is determined partly by the speed of the links involved and partly by the latency between the two endpoints - an effect known as bandwidth -delay product. In practice, this means that the perceived speed decreases the further away the two endpoints are.
Individual network owners typically use RED or WRED for congestion control. Traffic to customers with Point-to-Point fiber shapes in Kviknet's network with CoDel. The purpose of shaping is to smooth out bursts and thus ensure higher throughput on the individual customer's connection.


In some places in TDC's network you can get fiber via XGS-PON - here the speed is 2,500 / 2,500 Mbit / s. On the rest of TDC's network you can get 1000/500 Mbit / s, which is delivered via GPON fiber.
On Norlys' network, we deliver 1,000 / 1,000 Mbit / s via GPON fiber.
On EWII's network in the Triangle area, we deliver 1,000 / 1,000 Mbit / s via Point-to-Point fiber.
Nord Energi
North of the Limfjord, we deliver 1,000 / 1,000 Mbit / s on Nord Energi's fiber network via Point-to-Point fiber.
In OneFiber's coverage areas, we deliver 1,000 / 1,000 Mbit / s via GPON fiber
We exchange traffic with TDC in all major cities in Denmark. From here, the traffic is transported via our transport network to Tåstrup. Latency is typically between 1 - 2 ms. in the area around Tåstrup to approx. 8 ms. in North Jutland.


The speed available on the coax network depends on the load on the network in your area. This is because coax is a shared medium where you practically share the available capacity with your neighbor.

TDC continuously optimizes the network so that there is plenty of capacity for everyone, but in peak situations, speed can be lower than normal.
The stability of coax is affected by the fact that it is a network with many active components in street cabinets without emergency power. We therefore see more interruptions on coax networks than on DSL and fiber. Coax networks are also sensitive to electromagnetic noise, which is sometimes seen in the event of defects in connected equipment.


The speed of a DSL connection depends on the distance to the PBX. For shorter distances (a few hundred meters), up to 100/35 Mbit / s can typically be delivered via VDSL.
The stability of DSL connections depends on the quality of the telephone cable.
