Slack Outage Brings a Screeching Halt to Business as Usual


If you’re having trouble using Slack right now, you’re not alone. Everyone’s favorite workplace app is experiencing some connectivity issues this Wednesday, according to a status report from the company.

Reports that Slack was down for some people started to appear on Downdetector at around 7 a.m. PT, and have continued to spike ever since (Downdetector is owned by the same parent company as CNET, Ziff Davis). On Slack’s status page, the company first posted about the incident at 7:27 a.m. PT, saying that it was aware some users were having trouble using and loading Slack.

It seems that the the incident is affecting connectivity, messaging, logins, workflows, and apps, integrations and APIs. In my own testing, I couldn’t get Slack to load on my browser, but both the desktop and mobile apps were working just fine. But according to Downdetector, 60% of users were reporting problems with the app and only 17% with the website, suggesting people’s experiences of the outage may differ.

The latest message, posted at 9:26 a.m. PT reads: “Our investigation is still in progress with regard to deprecated functionality for Slack features such as workflows, threads, sending messages and API-related features.”

Slack also thanked users for their patience and said it would post more updates when it had more to share. The company has not yet released any details on what has caused the outage, and following a request for comment, pointed me back to the status update page. “Our teams are aware and are investigating the issue,” a company spokesperson said.
