No, it’s wasn’t just you. Slack indeed went down due to an outage of some sort that appeared to have begun some time around 7:30PM ET. User-reported issues spiked on DownDetector.com, and the app was largely inaccessible, with posts not getting marked as read or not going through at all. The issues affected both the mobile and desktop versions of the app. Slack says it’s in the process of resolving the issue, but connectivity problems remain for some users.
The entire world just suddenly got a whole less productive. Global outages like these ones really put our reliance on technology platforms into perspective.
