Telstra's national internet network went down for an hour today, the company says.

The outage affected all Telstra home and businesses broadband and mobile internet customers nationwide, between 7.50am and 8.50am, a spokesman said.









The company formed a major incident response team to investigate the outage. It's not yet known what caused it.



Another spokesman told Sky News that customers could not access any international sites or Australian sites containing international links.



Internet forums and micro-blogging site Twitter lit up with posts on the problem.

"Massive failure on Telstra's part this morning, their entire network, and hence ours, chewed up and spat out by the network god," one user wrote.
