Uptime This Week

Slack maintained perfect availability throughout the monitoring period, while Teams delivered 99.87% uptime—a difference of 0.13 percentage points. Both providers stayed well above industry standards, with Teams' 99.87% translating to approximately 11 minutes of potential downtime annualized. Neither provider experienced tracked incidents during this week.

Response Time

Slack responded to requests in an average of 161ms, outperforming Teams by 46ms (207ms average). This 22% response time advantage suggests faster user interaction and lower latency on Slack's infrastructure during the monitoring period. Both response times fall within acceptable ranges for web-based collaboration tools.

Incidents & Downtime

Both providers maintained zero incidents and zero minutes of downtime during the monitored week. This identical performance on incident frequency indicates stable operations for both platforms. However, Slack's official status dashboard provides public incident transparency, while Teams lacks a published status page for customers to monitor.

Historical Context

Collaboration tool providers have increasingly prioritized uptime consistency as remote work adoption solidifies. Leading platforms in this category typically target and deliver 99.9%+ uptime, making both Teams and Slack's performance competitive within their market segment.

Which Should You Choose?

For teams prioritizing absolute uptime, Slack's 100% availability and faster response times offer a slight edge during this monitoring period. Teams remains a solid choice for organizations already integrated into the Microsoft ecosystem, though the response time differential may impact real-time collaboration scenarios. Both are enterprise-grade reliable.
