Slack is the communication hub for millions of teams worldwide. When Slack goes down, team communication halts, workflows break, and productivity plummets. This guide helps you quickly determine if Slack is experiencing an outage and what to do about it.
Quick Status Check: Is Slack Down Right Now?
- Check API Status Check: Visit apistatuscheck.com/api/slack for real-time Slack monitoring
- Slack Status Page: Check status.slack.com for official status
- Try the Web App: Visit app.slack.com if the desktop app isn't working
- Check DownDetector: downdetector.com/status/slack for user-reported issues

Common Slack Error Messages
| Error | Meaning | Fix |
|---|---|---|
| "Trouble connecting to Slack" | Network or server issue | Check internet, try web app |
| "Something went wrong" | Generic server error | Refresh, restart app |
| "You've been disconnected" | WebSocket connection lost | Check internet, restart Slack |
| Messages stuck "sending" | Message delivery failed | Wait, message will retry automatically |
| Notifications not arriving | Notification service degraded | Check notification settings, restart app |
| "Unable to load workspace" | Auth or server issue | Clear cache, re-authenticate |
| Slow message delivery | Performance degradation | Server-side issue, wait |
| Huddle won't connect | Audio/video service down | Try regular call instead |
| Threads not loading | Partial outage | Check status.slack.com |
| Search returning no results | Search index issue | Server-side, wait for fix |
Step-by-Step Troubleshooting
Step 1: Confirm It's Not Just You
- Check apistatuscheck.com/api/slack
- Check status.slack.com
- Ask colleagues via text/email if they can access Slack
- Check Twitter/X for "Slack down"
Step 2: Try Alternative Access Methods
- Web app (app.slack.com) if desktop app is failing
- Mobile app if desktop/web is down
- Desktop app if web is down
- Different workspace to see if it's workspace-specific
Step 3: Restart and Clear Cache
Desktop App:
- Quit Slack completely (not just close the window)
- Mac:
Cmd+Qthen reopen - Windows: Right-click system tray icon → Quit
- Clear cache: Help → Troubleshooting → Clear Cache and Restart
Mobile App:
- Force close and reopen
- Clear app cache (Android: Settings → Apps → Slack → Clear Cache)
Step 4: Check Network
- Test internet at fast.com
- Slack requires WebSocket connections — some firewalls block these
- Disable VPN temporarily
- Try a different network (mobile hotspot)
- Check if your company proxy allows
*.slack.com
Step 5: Check Integrations and Bots
If Slack works but bots/integrations are broken:
- Check the specific integration's status (e.g., Jira, GitHub)
- Verify bot tokens haven't expired
- Check Slack API status at api.slack.com
- Review Slack app permissions in workspace settings
Step 6: Workspace Admin Checks
If you're a workspace admin:
- Check Slack admin console for any notifications
- Verify SSO/SAML configuration is working
- Check if any recent permission changes affected access
- Review audit logs for unusual activity
Historical Slack Outages
Notable Incidents
February 2022 — Major Global Outage
Slack experienced a widespread outage lasting approximately 5 hours during peak business hours. Users couldn't send messages, load workspaces, or access any functionality. One of the longest Slack outages in recent history.
September 2022 — Intermittent Connectivity
Repeated connection drops and "reconnecting" messages for 3+ hours. Messages were delayed by minutes, creating confusion as conversations arrived out of order.
May 2023 — Notification System Failure
Slack worked normally but notifications stopped arriving on all platforms for 4+ hours. Users had no idea they had new messages unless they manually checked each channel.
January 2024 — File Upload and Search Outage
File uploads failed and search returned no results for approximately 6 hours. Messaging worked but productivity was impacted as users couldn't share files or find past conversations.
August 2024 — Login and SSO Issues
Users were randomly logged out and couldn't re-authenticate for 2+ hours. Particularly affected organizations using SSO/SAML, locking out entire companies.
Outage Patterns
- Monday mornings: Highest load as global teams start their week
- After updates: Desktop app updates occasionally cause connectivity issues
- Notification reliability: Notifications are the most common partial failure mode
- WebSocket sensitivity: Slack's real-time messaging relies on WebSocket connections that are sensitive to network issues
What to Use When Slack Is Down
| Need | Alternative |
|---|---|
| Team messaging | Microsoft Teams, Discord, Google Chat |
| Quick messages | SMS group text, WhatsApp group |
| Video calls | Zoom, Google Meet, Microsoft Teams |
| File sharing | Email, Google Drive, Dropbox |
| Status updates | Email blast to team |
| Incident response | PagerDuty, Opsgenie (phone/SMS) |
Pro tip for teams: Establish a "Slack is down" communication plan. Pick a backup channel (e.g., "if Slack is down, check the team Discord" or "email the team distribution list").
For Developers: Slack API During Outages
// Check if Slack API is responding
async function checkSlackHealth() {
try {
const response = await fetch('https://slack.com/api/api.test');
const data = await response.json();
console.log(data.ok ? '✅ Slack API operational' : '⚠️ Slack API error');
} catch (error) {
console.log('🔴 Slack API unreachable');
}
}
API Rate Limits During Recovery
After an outage, Slack's API often experiences elevated rate limiting as services catch up. Implement exponential backoff in your integrations:
- Tier 1 (Web API): 1 request per second
- Tier 2: 20 requests per minute
- Tier 3: 50 requests per minute
- Tier 4: 100+ requests per minute
Frequently Asked Questions
Is Slack down right now?
Check apistatuscheck.com/api/slack for real-time status. Also check Slack's official status page at status.slack.com. If both show issues, Slack is experiencing an outage.
Why am I not getting Slack notifications?
Notification failures are Slack's most common partial outage. Check status.slack.com for notification service status. Also check: Do Not Disturb isn't enabled, notification settings are correct, and try restarting the app.
Does Slack have an SLA?
Yes. Slack guarantees 99.99% uptime for Enterprise Grid customers (about 52 minutes of downtime per year). Business+ and Pro plans have less strict SLAs. Check your plan details at slack.com/pricing.
How long do Slack outages usually last?
Most Slack outages resolve within 1-3 hours. Minor issues (notification delays, slow messages) resolve faster. Major outages have historically lasted up to 5 hours.
What happens to messages sent during a Slack outage?
Messages that were "sending" when the outage began are usually delivered once Slack recovers. However, messages typed during a complete outage may need to be resent. Slack's infrastructure is designed to prevent message loss.
