On October 8th between 5:55pm PT and 9:55pm PT, some customers were unable to connect to Slack’s mobile app. Affected customers were shown a connection error banner during this time.
At 5:55pm PT, we released a deploy which introduced an error in our code and prevented connections for customers using the app on their Android or iOS devices. Once we detected the issue, we reverted the deploy and customers were able to successfully connect to Slack again at 9:55pm PT.
We are hard at work on scoping preventive measures to ensure this doesn’t happen again in the future.
