Slack is experiencing a global outage

Messaging service Slack is experiencing a malfunction on Monday afternoon. Users of the service cannot exchange messages with each other or only sporadically. The cause of the malfunction is unknown.

Slack confirms that it is experiencing an outage, without providing details about the cause or when it should be fixed. The issues concern messaging and connections and appear to be global.

The outage comes at a time when many American workers are returning to work after the weekend and New Year’s Day. Slack is particularly popular as a business chat platform. Messages that users send each other do not arrive or arrive late and users have trouble connecting to the platform.
