Telstra has taken to Twitter to explain why their mobile coverage is playing up across the country.
The fire was at their Chatswood exchange in Sydney, Telstra confirmed at around 1:40pm.
Telstra confirmed that both mobile and landline services were impacted by the fire.
It’s unclear what caused the fire, which had now been put out.
It’s the second time in a year that fire has broken out at a Telstra exchange, after an electrical fire at the Brunswick facility in Melbourne in June last year.
