Business communications platform Slack is scrambling to recover from an ongoing outage that is proving disruptive to cybersecurity response teams around the world.
At 7:15AM PST, the San Francisco, Calif.-based Slack confirmed users were “having trouble loading channels or connecting to Slack.” No other details were provided on the cause of the outage.
Here’s the latest word from Slack:
“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.”
The company’s status.slack.com page acknowledged an “incident” affecting Messaging and Connections within the service, but users reported problems with a variety of Slack tools, including Search, Notifications, Workspace Administration and apps integrations.
Even the company’s flagship Slack Enterprise Grid, a product that powers security alerting and other critical messaging functions at global organizations, appeared to affected by the outage.
UPDATE (11:30am EST): Slack has upgraded this from an “incident” to a cross-service “outage” affecting logings, posts, files, calls, app integrations and APIs, connections, link previews, notifications and search.
“We’re continuing to investigate connection issues for customers, and have upgraded the incident on our side to reflect an outage in service. All hands are on deck on our end to further investigate,” the company said.
