Customers worldwide were unable to connect with Microsoft's 365 services and its cloud platform Azure on Tuesday, a problem the company says it is investigating and which has now been partly resolved.
According to Downdetector, an online outage tracker, the number of reports related to Microsoft services surged to more than 200 just before 9 a.m.
Problems with its Microsoft 365 administration centre and its coding tool collection Power Platform were resolved.
Azure, which is Microsoft's brand for cloud services, is a giant in the industry, said Carmi Levy, a technology analyst based in London, Ont.
It's the technology that underpins most of Microsoft's services, including Office 365, Teams, Bing and Xbox, he said.
