Slack Down: Normal service is resumed after 3 hour outage

Update (17:52pm BST): It’s over! Slack’s global outage has been resolved. The news was confirmed by Slack’s official Twitter account, and the official Slack status update page has been updated with the news. 

We’ve managed to get on Slack ourselves, and we can confirm that the service does now appear to be working once again after over 3 hours of downtime. 

Read on for the story of the outage as it happened…

It’s not just you, the popular business communications tool Slack really is down for everyone. 

The official Slack Twitter account @SlackHQ has confirmed as much in a recent tweet, and has now confirmed that it thinks it’s isolated the issue and is “getting close to a resolution”.

You can follow the outage over on, where the company confirmed that it had recognised the service as being down at 6:33am PDT (14:33 BST).

“We’ve received word that all workspaces are having troubles connecting to Slack. We’re currently investigating the issue, and will have updates shortly,” the company posted.

At 7:03AM PDT the company updated its status indicator to say that the team is still looking into the outage, however no new information was forthcoming.

At just past 4PM BST, the company issued another update to helpfully inform us that it has “no new information to share”. However, its accompanying tweet did confirm that the service is still in “rocky waters”.

The outage will have large implications for any businesses which rely on Slack for team communication such as Trusted Reviews, which has already had to resort to an intricate series of WhatsApp groups to maintain communication.

There has even been talk of communicating via email.

Nevertheless, the excellent timing of the outage having come just before South Korea’s World Cup match against Germany has not been lost on many Twitter users, who have been celebrating like a group of children sent home on a snow day.
