On the very first day of New Year, Slack suffered an outage across its various services.

As per the recording of Slack’s dashboard, messaging and connection went down first, but by noon EST, all of Slack’s services came down. However, the company pointed out that there was a little improvement observed in the working of Slack after clicking on the refresh button (CTRL/CMD R).

Later, all the services got restored around 3 PM EST.

The condensed timeline looks like this:

– For any customers unable to access Slack, please reload (CTRL/CMD R) or restart Slack. If you encounter any trouble, please let us know at [email protected]

– We’ll have a separate post on this site for the outstanding calendar apps and email notifications trouble.

– We’re truly sorry for the disruption today. We’ll be back with a summary of this issue.

Salesforce made a recent announcement that it was acquiring Slack for USD 27.7 billion with plans to grow the company’s Customer 360 efforts.

The talk about outage started popping up on Twitter and internal networks as soon as 2021 began. On the one hand, where the hope of a new normal started blooming, on the other hand, a new glitch was observed on Slack.

Those working on Slack might hear some more about such updates. Stay tuned to the Slack dashboard every half hour or so as the working might remain interrupted for some more time.
