Key Information
- Slack encountered issues with connectivity and thread loading early on Tuesday.
- The disruption was traced back to a backend database routing problem and was rectified by 5:37 a.m. (GMT+5:30).
- This incident marks Slack’s second major service interruption this year, following a global outage in February.
Morning Service Interruptions for Slack Users
On Tuesday morning, May 13, users of the widely-used workplace messaging service Slack experienced unanticipated service interruptions. The Slack Status page indicated that many users were struggling to send messages, load threads, or access crucial features like channels, canvases, and activity logs.
The origin of the issue was linked to a backend database routing difficulty, which hindered the platform’s capacity to provide real-time communication services. The engineering team at Slack acted quickly, pinpointing the cause and deploying a solution within a few hours. By 5:37 a.m. (GMT+5:30), service was fully restored.
Consequences and Actions Taken
Even though the outage occurred early in the day, limiting its impact on users globally, those affected reported issues accessing vital collaboration tools. Slack promptly recognized the problem and communicated updates through its status page.
“The issue has been resolved and users should now observe enhancements across all impacted features,” the company noted. Slack also recommended users reload the app to ensure seamless performance post-resolution.
Another Significant Outage in 2025
This incident represents Slack’s second major outage in 2025. In February, the platform experienced a global disruption that affected login capabilities, messaging, and other essential features. That issue persisted for several hours and impacted workplaces around the world, underscoring Slack’s essential role in contemporary digital communication.
In both instances, Slack’s engineering team reacted swiftly to identify and rectify the problems, but the recurring outages may spark concern among enterprise users who depend on the platform for constant collaboration.
Future Considerations
Slack has assured users that it is diligently monitoring system performance and addressing a small backlog of queued items resulting from the outage. The company has also reemphasized its commitment to bolstering platform stability and enhancing its backend infrastructure to mitigate similar occurrences in the future.
As remote and hybrid working environments increasingly rely on digital communication tools, the dependability of platforms like Slack remains crucial. Users are encouraged to keep informed via Slack’s official status page and report any ongoing issues through support channels.
