Sustainability
Hosting uses energy. Every page, every query, every deploy. We can't change that. What we can do is be honest about it, and make a -small- difference with the right choices.
Infrastructure
100% green energy
Our hardware runs on green electricity, generated by wind and solar energy. Not offset through certificates from abroad - the power is generated and consumed here.

30% less hardware, 50% less power
The typical server setup is active-passive: one location handles all the traffic while a second location does nothing and maybe acts as a failover once every five years - so 100% overcapacity at all times.
Our architecture is active-active: every location actively serves traffic, so we can get away with around 30% overcapacity to absorb a full outage rather than 100%. Plus, no hardware sits idle.
The result: roughly 30% less hardware and 50% less power consumption.
How we work
An eye for humanity
Just as we give our customers a solid (digital) foundation, we give our people a solid base too: fair salaries, real flexibility, and seriously invest in the growth of every team member. We expect a lot of our people (we have to: we host critical infrastructure), but you won't find an Elon Musk walking around here.
Daily choices
Bart van Overbeeke
How we get places
Wherever possible, our team travels by bike or public transport. We reimburse cycling costs and public-transport passes. We don't offer a lease-car programme. Our office is near Eindhoven station, so it's easy to reach by train.
Vegetarian by default
At the office, we eat vegetarian - and often vegan. It's the simplest daily choice with the clearest impact: the food industry is one of the largest contributors to emissions.
How we do business
European values
Digital independence is sustainability too: European values, European data centres, a European team. We've spoken out about digital sovereignty since we started in 2014.

Engaged in society
We think carefully about the impact of technology on society. We were among the first to support the referendum against the Dutch intelligence services surveillance law (the 'sleepwet'), and we think critically about AI in our own work.

Open source contributions
We regularly donate to open-source projects and advocacy organisations, including Bits of Freedom, Borg, Pydantic and Celery. Everyone should be investing in the ecosystem that keeps the internet running.
We also publish our own open-source projects and contribute upstream fixes when we find bugs.
A clean internet
We respond to abuse reports faster than the average. Malware, phishing, spam - if it's on our network, we act. The industry average is three days; we don't need three days.
According to independent research by abuse.ch, Cyberfusion had the fastest response time in the Netherlands.

Honest storytelling
We skip the greenwashing. Slapping a "sustainable" badge on your website is easy. Actually explaining what you do, why, and where you fall short - that takes more effort. We take that effort, as this page itself shows.
