Hi @saradindusinha,
Welcome to the Community!
We apologise that your service is currently interrupted. I've managed to locate your account using your Community details and it showed that the issue is caused by a network outage.
Telstra have indicated they will aim to restore service by 19/02/2019. I understand that this is quite a timeframe for a resolution but please be assured that our wholesale partner is doing their best to resolve the issue in the soonest time possible.
Our Engineering Team will be in touch to provide further updates.
Thank you.
