Tornado Datacenter will execute a power upgrade of the FRA1 datacenter. This requires a temporary switch-off from the public power grid (Blackout Island Mode). To ensure stable operation, the switch-off will be executed in the following principle:
1. Emergency Generator is torougly tested and serviced in advance 2. Emergency Generator is started and operated without load for 30 minutes 3. After 30 minutes, the datacenter load is transferred onto the generator 4. The datacenter will operate another 60 minutes on generator, ensuring it's stability 5. Electricans will execute the required works to increase electrical capacity towards NSHV (ca. 30-60 minutes)
We do not expect any impact to customers. IT-Load stays UPS protected (A+B) during switching operations, our engineers will closely monitor the whole process.
