A major power-failure at the largest network hub in the Netherlands, the NIKHEF, has caused VoIP connection failures for our customers. No phone calls were possible for about 12% of our customers. The downtime started around 21.05 and lasted till 22.00 for about 8%, and 23.10 for the remaining 4% of our customers.
We apologize for the problems caused by this downtime.
The NIKHEF power-failure resulted in loss of Internet connectivity for many dutch based providers, including KPN Business DSL. But also international connectivity was affected, due the major international network role of the AMS-IX. The NIKHEF data-center hosts more than half of all foreign and domestic AMS-IX peering traffic. The graph below shows a clear ‘dip’ in the AMS-IX traffic curve, showing more that 50% lower data traffic starting around 21.00 CET.
AMS-IX announced via ANP news that further investigation is needed to determine the cause of the sudden, but complete power-loss in their primary data-center.
