Furthermore we own and operate 5 data centres with a total floor space of more than 4,000 square meters to provide co-location.

Network and internet traffic

Our optical fibre network is constructed with full redundancy and Quality of Service (QoS), and it runs with up to 10 Gbit/s. Accesses are typically established with 1 Gbit/s. With this unique network we can guarantee the highest speeds and the lowest latency on the market.

Nianet has several transit suppliers providing internet capacity, and Nianet is a peer entity on selected internet exchanges (IXs), which ensures high uptime on internet traffic. Nianet has also set up private peer entities with a number of major providers.

The equipment used in Nianet’s network infrastructure is based on Cisco’s latest technology. This is to ensure highest level of stability and to maintain an advanced security.
