The incident, which coincided with separate outage reports for AWS and Google, underscores how disruptions to major cloud providers can ripple across workplaces that rely on email, chat and collaboration tools for daily operations. Amazon's statement distancing itself from the issue suggests confusion among users about which company's infrastructure was actually responsible, highlighting the interconnected and sometimes murky nature of cloud service dependencies.
- Microsoft 365 outage hit Outlook, Teams and Exchange Online starting around 1 p.m. Thursday.
- Microsoft attributed the disruption to unexpectedly unavailable servers straining remaining infrastructure.
- Amazon denied AWS issues were related, calling some reports inaccurate amid a separate internet disruption.
