From Slack via Twitter:

For any customers unable to access Slack, please reload (CTRL/CMD + R) or restart Slack. If you encounter any trouble, please let us know at [email protected].

We’ll have a separate post on this site for the outstanding calendar apps and email notifications trouble.

We’re truly sorry for the disruption today. We’ll be back with a summary of this issue.

Jan 4, 3:10 PM EST

We’re seeing improvements with error rates on our side, and we believe affected customers should be able to access Slack.

We’re continuing to work to resolve the trouble with calendar apps and email notifications.

Jan 4, 2:28 PM EST

For those customers who are unable to access Slack (e.g. seeing a blank screen or error), please try reloading (CTRL/CMD + R). If you can access Slack, please hold off on reloading at this time.

In addition, Google Calendar and Outlook Calendar aren’t working as expected, and some email notifications (e.g. a notification of a new direct message in Slack) are failing to send.

Note: We’ve updated this message to specify holding off on reloading if you can access Slack.
