Network & connectivity

Low latencies throughout the world, due to our 1,000 Gbit backbone


Our network is the heart of our company. We have spared no investment to be able to eliminate bottlenecks and failures in their entirety.

firstcolo Backbone

To ensure the best possible connectivity to every endpoint, our traffic mix consists exclusively of tier-1 carriers and our customers benefit from the resulting high availability of our sites. Through our direct connect to the world’s largest peering point, DE-CIX, we realise the lowest latencies within our infrastructure. In addition, we enable a direct connection and optimal connectivity to over 1000 networks. We have upgraded our backbone to 1000 Gbit/s in order to offer our customers strong protection against cybercrime such as DDoS attacks. Therefore, even large DDoS attacks can be mitigated without any problems or impact on a customer’s infrastructure.

At the same time, our strong backbone allows us to realise a much higher uplink capacity for customer racks than is the norm with other service providers. In addition to redundant 10 Gbit uplinks as standard, our offer also includes up to n*100 Gbit uplinks for customer racks.

Also, the comprehensive range of IP transit services is no problem at our points of presence. This means you can benefit from our backbone regardless of data centre location. 

The choice of carrier plays a decisive role for reliability, connection quality and latency.

For best results in all areas, we currently operate direct uplinks to the following carriers:

100 Gbit/s DE-CIX

100 Gbit/s NL-IX

400 Gbit/s GTT

200 Gbit/s Telia

200 Gbit/s NTT

400 Gbit/s Cogent

100 Gbit/s

The heart of the Internet: In Frankfurt am Main.

A few minutes walk from the largest Internet hub in the world.

Dense-Wavelength-Division-Multiplexing (DWDM) Fibre Ring

In addition to our first-class carrier network, we also operate a 1.2 terabit DWDM fibre ring throughout Frankfurt. This allows us to connect our in-house data centres with our external locations within Frankfurt, thereby transporting business-critical data at high speeds and with the lowest latencies. 

In addition, the existing DWDM route is already designed for the next technological leap to 400 Gbit/s. This enables us to being able to meet the high demands of our customers in the future.

Redundant Dark Fibre

In order to realise an adequate data centre interconnect (DCI), we have built a redundant dark fibre connection between our in-house data centres in Frankfurt am Main some time ago. Users benefit from optimal connectivity and low latencies between our sites.

To minimise the risk of a failure, we have also deliberately designed the dark fibre connection as redundant. Like this, we can offer geo-redundant backup concepts and encrypted data transmission, as well as dedicated wavelengths on our DWDM equipment.

Guaranteed Performance

Our entire network design is entirely redundant. All used components are constantly kept in our data centres at least once more than is necessary for productive operation. We consistently adhere to this standard, so that we can react immediately if necessary and prevent downtimes at any time. In addition, our network is not overbooked, and we do not use any uplink to more than 50 percent of its capacity. Like this, we avoid short-term bandwidth bottlenecks. Peak times or short-term peaks are therefore just as little of a problem as short-term ad-hoc expansions. With us your infrastructure remains highly available at all times.

Our partners

A universal routing platform – with Juniper’s MX Series.

With high 10/40/100 GbE port density, the redundant MX routers are ideal for all mission-critical workloads and cloud applications. With a throughput of up to 2.4 Tbps in just three height units, the series includes some of the most performance-optimised routers on the market. Our superior routing infrastructure allows us to easily implement customer setups with any bandwidth.

Arista‘s platforms achieve data transfer speeds of up to 400 Gbit/s and set new standards for scalability, agility and availability. Software-driven cloud networking ensures that you are always prepared for future workloads. Like this, Arista offers world-class products to large data centre service providers and cloud infrastructure operators.

We also trust the market leader and use Arista equipment within the entire firstcolo infrastructure.
