On Tuesday, businesses across the world—including major Australian companies—reported widespread issues with the platform.

This failure led to spikes in errors across numerous Slack features, affecting users in various regions around the globe.
“We have determined that our backend database routing is contributing to error spikes with many Slack features,” the company stated in a public update. “This is not limited to a region and is impacting a percentage of users globally. We are working to determine full impact.”

“We made a change and are seeing signs of improvement across Slack,” the company said. “Users will see success in sending messages, loading channels, threads, canvases, and Activity, as well as client boots. We apologise for any disruptions to your day.”
