Underground bunker data centre

This World Backup Day we're opening a second hosting location: deep underground in a former Cold War bunker, a stone's throw from Hazerswoude-Dorp.

This unique site, internally known as Bunker Harde Hosting, offers a surprising number of benefits:

  • Constant temperature and humidity without active cooling
  • Concrete walls almost a metre thick for physical security and uptime
  • Shielded from above-ground risks such as power outages and fibre cuts
  • Probably EMP resistant 😉

The bunker was originally built for critical communications during crises, but it turns out to be a perfect fit for a data centre as well. We've reconfigured part of the space for energy-efficient servers and off-site backups. Fits well with how we think about sustainability and continuity.

The coffee on-site is, unfortunately, questionable and expired sometime in 1989.

We're finalising the preparations. The uplink is almost ready. We'll soon share more photos from inside the bunker along with a layout of the setup.

For now, enjoy a first impression through the images above.

Happy World Backup Day!
