Deutsche Telekom has confirmed up to 900,000 customers have had their broadband service cut off following a possible hack of its hardware.

The number fell to 400,00 as security measures were implemented. Internet access, phone connections and TV reception for those with a certain router have been affected since Sunday.

Deutsche Telekom has issued a software update and is asking affected customers to disconnect their routers. In a statement, the company said that ‘based on the error pattern, we cannot exclude the possibility that the routers have been targeted by external parties with the result that they can no longer register on the network.’ (29th November 16)
