Slack, the widely used workplace communication platform, has fully restored its services following a major outage that disrupted messaging, workflows, and connectivity for thousands of users worldwide.
The outage began around 10:30 a.m. EST, with users reporting difficulties in sending messages, loading threads, and using API-related services. The issue primarily affected users in the United States, United Kingdom, and other regions.
Slack’s engineering team identified the root cause as problems with database shards, which led to instability in multiple features. The company worked quickly to diagnose and resolve the problem, gradually restoring services throughout the day. By 4:42 p.m. PST, full functionality was reinstated across all affected components.
During the outage, Slack advised users to reload the platform using specific keyboard shortcuts to refresh their connection. The company has since apologized for the disruption and expressed appreciation for users’ patience.
This incident highlights the critical role of communication platforms in modern workplaces, where even short-term disruptions can impact productivity on a large scale. Slack has assured users that it is taking measures to prevent similar issues in the future.
