The notification underneath refers:
Although the GRHub Network has a fully back-up power system the power outage is the ideal opportunity to upgrade the back-up and main power systems of the GRHub Network. A new 100 Ah battery will be installed as well as several power down converters. I envisage that the Network will be off line and off air for 2 - 3 hours on 18 October 2021. The power outages might be an inconvenience but on the other hand gives me the time to do upgrades to enhance the operation capability of the GRHub Network.
