Business communications and collaboration platform Slack is currently experiencing outages for “some users” across the globe.

Some businesses are currently unable to load their workspaces, sign out of accounts, or use any features on the platform including messaging and calling colleagues.

“Some customers may be experiencing issues with loading Slack,” the company said in a tweet from its status-checking account. “We'll provide a status update once we have more information. We're sorry for the disruption.”

Slack first started investigating the issue at 14:25 PM (GMT), according to its status page, and provided an update at 14:44 PM (GMT) saying “we’re still working towards a full resolution. We’ll be back with another update soon. Thank you for your patience.”

Its most recent update, at the time of writing, came at 15:23, an hour after the first acknowledgement of issues. Slack said it is continuing to investigate the issues but did not add any insights into what was causing it or how many users are affected.

According to affected users, the platform appears to be inaccessible through its desktop and web apps, and the platform is failing to load for smartphone users too.

Users have attempted to sign out and sign back into Slack, but users on computers are met with ‘sign out’ links that do not work, while mobile users receive an error saying they must be connected to a network in order to sign out.

Other Slack users seem to be less affected by the service issues, only reporting faults with threads and direct messages.

Service outages are common with collaboration platforms and are usually resolved expeditiously.

The outage will be impacting a large number of organisations worldwide. Slack last reported its daily active user (DAU) figures in 2019, saying it had more than 10 million at the time.
