Is Microsoft login intermittently loading for anyone else in Australia?

There are reports of Microsoft 365 and Azure services being affected, not just the login page. The symptoms vary: some connections have trouble with Teams while SharePoint works, and others can't reach SharePoint or OneDrive either.

Microsoft's service health advisory MO1411776 describes a third-party networking issue affecting access to Microsoft 365 in Australia. That fits the broader symptoms, though it doesn't establish the cause of every individual connection failure.

Check the network path before spending too long on the browser. Several reports involve Telstra connections, including business services and upstream paths. Try the same login endpoint from another connection, such as a mobile hotspot, and compare the results.

A successful hotspot test points toward a path-specific problem, but it won't prove which provider or network hop is responsible. Results aren't uniform across providers either.

DNS is worth checking, but don't stop there. One report had unexpected search suffixes being added on some domain-joined Windows machines, while another found the same DNS addresses on working and failing connections. Flushing DNS also didn't help in one case.

Compare the lookup and connection results from an affected device and a working network. If resolution is consistent but the connection times out, pass those details to the network provider rather than assuming the name lookup is the problem.

For organisations with alternate routing, there was a report of restoring access for some users by sending traffic through a Sydney SD-WAN path instead of the direct Telstra path. That's a possible workaround to test, not a confirmed general fix.

Peering has been suggested as a cause, and there was a report that Telstra had acknowledged an issue without a fix time. The available reports don't establish the exact fault.
