Telstra technicians have been working on the difficulty since it was reported on January 2 and are -still in the thick of the problem", spokesperson Stuart Gray told ZDNet Australia.
"They're working through all the possible scenarios and eliminating them one by one," Gray said, adding that as yet there is no estimated time of repair.
Telstra has tagged the problem as an -intermittent and low-level issue", with the intermittence making it difficult to pinpoint the root cause of the problem.
Vendors are also said to be investigating what is believed to be a software or hardware issue. "It's not characteristic of a Denial of Service attack," Gray said.
Telstra is helpless and useless, but this does not prevent them to commit day light robbery.
