In order to maintain network performance and reliability, network maintenance will be carried out during the night of Saturday to Sunday (20 October 2019).
Several core network components will be updated, upgrade or replaced. This has to be done to address increasing throughput requirements and to guarantee 24/7 reliable network operation.
Due to the scope of the maintenance, a short interruption will be unavoidable.
Redundancy measures will keep the impact to a minimum.
