Finland fears “congestion”. But for now there are no disruptions
However, the cable fault did not lead to internet connection problems in Finland. International telecommunications connections in Finland have been secured on several routes. “The impact on the citizen may be minor, but it causes congestion on other cables when one is not in use,” said Samuli Bergström, head of anomaly management at Traficom's cybersecurity center.
However, this does not change the fact that the cable needs to be repaired. A repair ship is scheduled to arrive on site France. Repair requires lifting the cable from the seabed. Its repair is expected to take 5 to 15 days. – This is not an everyday occurrence, but it is not a dramatic situation either – reassured Bergström.
