Slack outages and problems

How to fix Slack not working
Slack is up on our end, so if it won't work for you, the problem is most likely on your side. Work through these in order:
Check Slack's live status first
Slack currently reports operational, with 100.00% uptime over the past 24 hours and 3 outage reports. That gives a quick answer to searches for is Slack down and is Slack down right now, while the Slack server status shows when the last outage happened, more than 24 hours ago.
Refresh the Slack app session
If Slack not working today is the problem, quit the desktop app, clear its cache, reopen it, and sign in again; browser users should reload the workspace tab after clearing its site data. Check is Slack working from another device before changing local settings.
Check your network and DNS
For a Slack down detector result that points to your connection, test another site and switch networks; if both fail, restart your router. If Slack outage today 2026 reports keep rising, check Slack network status before changing DNS settings, since a wider failure will affect multiple connections.

How we track Slack
The status on this page comes from user-submitted problem reports for Slack, counted in 15-minute windows over the last 24 hours. Each window is compared with the normal level for Slack, so a few complaints on a quiet day don't trigger anything, but a sudden jump well above normal does.
When reports climb well above normal, the status here changes to partial outage or major outage and the chart moves with it. This is separate from Slack's official status page: user reports tend to show a problem early, while the official page confirms the cause. If the two disagree, check both.
