Data centres are built to last 20 years. The climate in 20 years will bear no resemblance to today’s.

Why am I telling you this? I regularly run workshops (the Climate Fresk) designed to understand how the climate really works and what that means for us, as humans.

No activism or grand speeches here: it is mostly popular science, laid out collectively so that everyone can understand.

The aim is to reflect the view of the scientific community and to map the risks.

The ones we see clearly, such as heatwaves or extreme weather events. And the ones we tend to underestimate, which are less obvious because they are slower or less spectacular.

Applying this “thinking in terms of risk” logic, I couldn’t help asking myself: what are the major dangers France-IX must take into account? How do we absorb the shocks?

For example, as a peering infrastructure, there are data centres, cables and equipment running around the clock. And like any physical asset, it is exposed.

The question is not whether these risks exist; it is to measure and anticipate them in order to protect ourselves.

Trying to avoid everything is a dead end. What matters is the ability to absorb shocks and to maintain continuity for our customers when conditions deteriorate.

Today, resilience and robustness are not pretty promises; above all, they are scenarios to plan for in order to protect your business.
