We have an interesting problem in the office today: Slack is down, and we can't tell anyone. We've had to resort to email and actually talking face-to-face to make each other aware of the issue.

In the past hour Down Detector has received multiple reports of Slack outages in the UK and US. The problem is associated with both the desktop and mobile apps.

The company has confirmed it is experiencing problems, stating that: "We've received word that all workspaces are having troubles connecting to Slack. We're currently investigating the issue, and will have updates shortly.

"Our team is still looking into the cause of the connectivity issues, and we'll continue to update you on our progress."

For future Slack problems, here are a few ways to check whether Slack is down or if it's just you:

How to tell if Slack is down

  1. Check Down Detector for a Slack status report
  2. Check Twitter for posts on Slack
  3. Check with other Slack users - face-to-face, over the phone or on email
