Zero Carbon

Renewable Energy

Your hardware is fully powered by renewable energy.

Located in Switzerland

Our data center locations are based in Glarus in the middle of Switzerland. Not only is it one of the safest places on earth, it is also naturally cool.


Your colocation can be fully customised to your needs. Space, connectivity, IPv4 and IPv6 addresses can be freely configured.

At Data Center Light we don't use traditional racks. Instead we give each server enough space (on average 4m² surrounding area). This way we don't need to actively cool.

How it works

If you want to bring your own hardware, you can select from the following options:


For one server we provide you with 1m² of physical shelf space. We call this our "base unit". Your server can be 1U, 2U or even 4U high. Contact us for special sizes.

We expect your server to not create more warmth than 3000 BTU/h. If it produces more heat, you will need to add more base units.


Your electricity usage is monitored and charged monthly. The price for electricity is 0.2 CHF/kWh.


We offer 3 levels of connectivity:

  • 10 Mbit/s (burstable 1000 Mbit/s) - 15 CHF/month
  • 100 Mbit/s (burstable 1000 Mbit/s) - 75 CHF/month
  • 1000 Mbit/s - 400 CHF/month

10 and 100 Mbit/s are calculated on the 95% rule. Most customers select the 100 Mbit/s option. Bandwidth exceeding the booked tarif is charged at 2.5 CHF/Mbps.

You get a multi mode fiber cable (850nm transceivers) to your shelf.

IP addresses

  • Colocation includes a /48 IPv6 network for free
  • IPv4 addresses are provided using NAT64 for 9 CHF/IPv4 address/month

Setup Fee

The one time setup fee is 100 CHF. It includes configuring a VLAN dedicated for you and adding routing to your own network.

Sample calculations

  • 1 base unit, 100 Mbit, /48 IPv6, no IPv4 = 50 + 75 = 125 CHF/month
  • 2 base units, 100 Mbit, /48 IPv6, 2 IPv4 addresses = 250 + 75 + 29 = 193 CHF/month
  • 4 base units, 100 Mbit, /48 IPv6, 40 IPv4 addresses = 450 + 75 + 409 = 635 CHF/month
  • 4 base units, 1000 Mbit/s, /48 IPv6, no IPv4 = 4*50 + 400 = 600 CHF/month
