Thank you for you patience. After Slack being down for about four hours for most of our customers, we are confident that the measures we've taken to restore service are functioning as expected. At this time everyone should be able to connect to and use Slack, including messaging, reacting, uploading, and all the other features that were impacted this morning. We are monitoring the changes we made to restore service closely and expect that at
4pm PST we will give the all-clear. We are extremely sorry for the interruption this has caused.
