London residents lose Outlook, Teams and Copilot for over ten hours

An outage that began on 29 July 2026 kept Outlook, Teams and Copilot offline across London for more than ten hours. Downdetector recorded a peak of about 140,000 Outlook reports before the number fell to 28,000. Microsoft says the cause was elevated load, not a security breach, and services are now partially restored.
