We ran into an issue during our planned move of the GitHub and Slack integration to a new data center on Saturday, March 14 and were unable to complete it. The issue has been resolved and the move is now scheduled for Saturday, March 21, 2020 from 4-5 PM (Pacific).

During this time, slash commands (like /github subscribe), link previews (unfurls), and notifications will not be available from Slack. No other GitHub.com services will be impacted.

Thank you for your understanding as we work to improve the integration between GitHub and Slack.
