Across our facilities, we offer multiple megawatts of total power capacity. By default we deliver fully redundant A+B power feeds of up to 32 Amps per rack per client, and we use no-break diesel generator UPS units — owned and maintained entirely by our own in-house technical team. With our own 10kV transformers and options for additional transformers, we never run short on power during expansions.

Our backup power supply provides 100% coverage for all facilities in the building, both office units and air conditioning, and is watched continuously by our own extensive monitoring. Your server equipment is kept constantly on UPS power. In the event of a power outage, our diesel generators take over the power supply — our diesel reserve guarantees 72 hours of backup for the entire building, backed by contracts for rapid fuel delivery.

In cooperation with our energy grid operator (Liander), we perform a 'black building' test twice a year — because extreme reliability isn't something you assume, it's something you test.

At the heart of every power feed is our main distribution board — where incoming grid power, transformers and generator backup all come together before being split out, feed by feed, to every rack.

Every switch and breaker is monitored and logged in real time, so load, status and any fault are visible to our engineers immediately, not discovered after the fact.

Clean, stable sine waves on every phase — that's what our UPS output looks like under normal load, measured directly on the unit.

Voltage, frequency and waveform are continuously monitored, so any deviation is visible immediately, long before it could affect your equipment.
