“Customers may have trouble loading channels or connecting to Slack at this time. Our team is investigating and we’ll follow up with more information as soon as we have it. We apologize for any disruption caused,” a message read about 10:44 a.m.
The company promised to update its site with status reports every 30 minutes until the issues are resolved. According to the Downdetector live outage map, Slack users in New York, Atlanta, San Francisco, Boston, St. Louis and Houston were reporting the most issues with the site.
Internet service outages are not uncommon, are usually resolved relatively swiftly and are only rarely the result of hacking or other intentional mischief. Google went down briefly in December, with people in several countries briefly unable to access their Gmail accounts, watch YouTube videos or get to their online documents during an outage. In August, Zoom went down briefly just as many students were beginning the school year at home. And, in September, Microsoft services had an outage that lasted for five hours.
