Slack Experiences a Brief but Widespread Outage


Slack, the widely used messaging platform, experienced an outage of just over an hour early Thursday, disrupting life in offices around the world (including this reporter’s).

The 65-minute disruption began at 5 a.m. Eastern time, after a change was made to the service that manages Slack’s internal system communication, the company said on its website.

During the downtime, the company said, “Users may be experiencing trouble with sending messages, using workflows and various other actions in Slack. We’re investigating and will let you know as soon as we know more.”

At 6:13 a.m., the company said, “Slack is now back up. Users may need to reload their apps to see this restoration.”

Slack has become an essential workplace tool. The company, which was founded in 2010 and was bought a decade later for $27.7 billion, says the platform is used by more than 100,000 companies.

Widespread internet outages are less common today than they used to be, as major tech companies have develop interconnected data centers that improve performance. But there have been disruptions, including at Slack, which suffered an hourslong outage on the first Monday of 2021, just as office workers were returning from the holidays.
