Between 12:54:00 and 12:56:30, we had a short network disturbance at our FFM2 location due to a failure of the wdm connection towards FFM3 (Interxion), where most of our traffic goes through. The disturbance itself was only around 20 seconds long, but might have impacted connectivity towards other ISPs due to flapping BGP Session. Therefore, we have determined a total incident timeframe of 2 minutes and 30 seconds.
The issue was self resolved, traffic has automatically been rerouted during the failure. For most customers, this incident was not noticeable. We have taken extra measures to avoid such a event from happening again.
