Is Slack down, or is it just you?
Multiple independent check rounds from rimetry's monitoring infrastructure, run seconds apart.
Our checks reached Slack successfully in every round of the last check cycle.
| Check round | Last check | Success rate (24h) | Avg response |
|---|---|---|---|
| Round 1 | Reachable | 100% | 947 ms |
| Round 2 | Reachable | 100% | 888 ms |
| Round 3 | Reachable | 100% | 697 ms |
| Round 4 | Reachable | 100% | 775 ms |
Based on 3,236 automated checks in the last 24 hours. Each round is an independent pass over the same endpoint, seconds apart — a single failing round is not an outage; repeated failures across rounds are.

About Slack
Slack is a workspace productivity tool used for team communication through channels, direct messages, and huddles. It integrates with various third-party apps and provides file storage alongside its searchable message history. Outages frequently impact the delivery of desktop notifications, the ability to upload files, or the loading of specific integration workflows like Slackbot or Workflow Builder. Rimetry keeps a constant watch on the accessibility of the Slack API and web client to confirm if the platform is experiencing technical difficulties.
Problems with Slack can affect login & authentication, messaging, voice independently.
Slack (slack.com) is a communication service monitored continuously by rimetry's automated checks. We probe its public endpoints every 60 seconds in repeated independent rounds to detect outages and latency spikes the moment they happen.
Right now Slack is reporting as operational across our probes, with an average response time of 225 ms and 100.00% uptime over the last 24 hours. Most users connecting to slack.com are seeing it work normally.
Common causes of disruption for services like Slack include backend API failures, region-specific routing problems at the CDN or ISP layer, expired TLS certificates, DNS misconfigurations, and capacity spikes during major events. rimetry combines automated probes, vendor status feeds, and verified community reports to give you a single high-confidence answer instead of guessing.

Slack is part of our Communication category. You can also review current trending outages across the internet.
Common issues
- · Messages stuck sending

- · Login or device-linking errors
Similar patterns often surface across other communication providers — cross-check against the global outage map.
Troubleshooting
- · Test signing in from a private browser window or another device
- · Send to a different chat to see whether it's account-specific
- · Switch voice region or server if calls fail to connect
- · Check notification permissions before reporting missing alerts
- · Check whether messages fail to send or fail to arrive — they're different problems
- · Test a call on mobile data to rule out firewall or Wi‑Fi restrictions
- · Restart the app so it re-establishes its websocket connection
- · Confirm notification permissions if alerts are silent
- · Try the web client to see whether the desktop app alone is affected
- · Check Slack's official social channels
