The company said Monday morning“Customers may have trouble loading channels or connecting to Slack at this time. Our team is investigating and we will follow up with more information as soon as we have it. We apologize for any disruption caused.”
Users began reporting issues around 10 AM, and the company posted its first status update about the problem at 10:14 AM. As of 12:29 PM ET, the service appeared to be slowly returning to normal for some users
Slack began reporting issues with connecting to the service including messaging. At 11:20 AM there was an update on its status page that upgraded the situation to a full-blown outage, with all aspects of Slack including logins, messaging, calls, and connections appearing as unavailable.
“All hands are on deck on our end to further investigate,” according to the update page.
Monday’s outage came as Slack is in the process of being acquired by cloud-based software company Salesforce.com for $27.7bn. The deal is aimed at giving the two companies a better shot at competing against longtime industry powerhouse Microsoft. Slack shares were down about 1% late Monday morning.
Slack previously grappled with outages in 2019. The company revealed in its September earnings report it lost $8.2m in revenue after issuing credits to customers whose services were disrupted. Its stock tumbled 14% in the aftermath.
So sorry, we are investigating some connectivity issues right now. Thanks for your patience!
