BUSINESSES affected by a fire that hit the Telstra exchange in south-western Victoria will be able to claim for compensation.

An estimated 60,000 customers internet and phone services were affected, following the fire at the Warrnambool exchange in southwestern Victoria on November 22.

Now Telstra says business customers affected by the outage will be able to claim compensation, with a call centre, online claim forms and visitations to affected areas set up.

Telstra says it has restored all mobile services and repaired 92 per cent of landline services as of last night.

Around 50 per cent of internet services were back on line as technicians worked to individually re-cable remaining landline services through the Warrnambool exchange.
