Technology giant Microsoft has apologised after thousands of people across the world reported issues with its products, ranging from email service Outlook to the hit game Minecraft.
Downdetector, which tracks websites, showed thousands had reported problems on Tuesday afternoon.
The issues appeared to be mostly resolved by the evening, according to updates from the company.
The incident came less than two weeks after a major global IT outage left over eight million computers using Microsoft systems inaccessible, impacting healthcare and travel, after a flawed software update by the cybersecurity firm CrowdStrike.
“It seems slightly surreal that we’re experiencing another serious outage of online services from Microsoft,” said computer security expert Professor Alan Woodward.
“The culprit appears to be network infrastructure but you would have hoped that with such important cloud-based systems there would not be a single point of failure.
“You’d expect Microsoft’s network infrastructure to be bomb-proof.”
An alert on the technology giant’s service status website said the outage affected Microsoft Azure – the cloud computing platform behind many of its services – and Microsoft 365, which includes systems like Microsoft Office and Outlook.
It also listed its cloud systems Intune and Entra as among those impacted.
Microsoft said it had implemented a fix for the problem which “shows improvement”, and it would monitor the situation “to ensure full recovery”.
“We sincerely apologise for the inconvenience,” it said in a post on X, formerly Twitter.
“Our experts are currently investigating the situation in order to resolve it as soon as possible.”
By Tuesday evening, Microsoft said most of the issues had been resolved. Its status site showed Microsoft 365 services available and the company said its Microsoft Azure service was in the “final stages” of recovery.
The outage appears to have impacted other services which rely on Microsoft’s platforms, with Cambridge Water among those affected.
“Due to worldwide issues with Microsoft Azure, a problem with our website is affecting several services including MyAccount and PayNow,” it said in a post on X.
The HM Courts and Tribunals Service – which is responsible for the administration of criminal, civil and family courts and tribunals in England and Wales – said it was aware of issues with “multiple online services”.
Some customers of NatWest also reported issues.
A spokesperson told the BBC: “We are aware that some customers experienced difficulties accessing our webpages today. This was linked to the issues reported by Microsoft Azure which has affected some Microsoft services globally.
“The issue has now been resolved and our webpages are functioning as normal. We apologise to customers for any inconvenience caused.”
Meanwhile, top flight Dutch football team FC Twente tweeted an update to their fans to say its ticketing website and club app were unavailable to supporters as a result of the outage.
The issues with one of Microsoft’s premier products appeared hours before the tech giant was due to provide its latest financial update.
Microsoft Azure has been a key profit driver for Microsoft in recent years.
But demand has slowed in recent months, rattling investors.
Shares in the firm dropped more than 5% in after-hours trade on Tuesday after the company reported weaker growth than expected in the April-June period.
Revenue in the “intelligent cloud” unit rose 21% year-on-year in the quarter, Microsoft said.
Overall revenue increased 15% to more than $64bn (£82bn), while profit rose 11% to $22bn.
