Telstra Internet users were without e-mail access for over three hours on Monday night, after a corrupted data file was found in a domain name system server.
Kerrina Lawrence, public affairs manager for Telstra Retail, said bigpond.com and telstra.com users may not have been able to browse the Web either.
“After 6pm on Monday we recalled staff as our monitoring tools detected a corrupted data file in the DNS [domain name system],” she said.
“The main issue Telstra Internet users would have had was being unable to send or receive e-mail. This [problem] is an unforseen issue and we managed to restore service after 9pm.”
Internet users that contacted PC World claimed e-mails to Bigpond accounts terminated after several minutes.
Telstra posted an alert on its service status page as well as setting up a recorded voice announcement on its helpdesk phone line.
Lawrence said about 1000 bigpond.com (dial-up) users were affected.
