Twitter is not working or extremely slow in loading, causing frustration for its Australian user base.
Downdetector, a website that tracks service outages through a range of sources including user reports, said the prolonged interruption began around 6.30am AEST.
Users took to other social media platforms to express their dissatisfaction with the latest disruption - the second in as many weeks.
"Twitter website slow as and wont load. $13AUD month and Elon can't even keep a website up," one user wrote referring to eccentric Twitter billionaire owner Elon Musk's subscription plans for verified accounts.
Another user Prodos Marinakis tried a workaround solution changing his VPN location to no avail.
"I'm in Australia & on a laptop. Just tried using USA VPN. Unfortunately, no luck with that."
The outage comes two months after Mr Musk's $US44 billion ($A65 billion) takeover of Twitter, which has been marked by chaos and controversy.
Hundreds of Twitter employees quit the social media giant in November including engineers responsible for fixing bugs and preventing service outages.
