Slack is down, massive outage blocks user logins and messages

Slack is experiencing a worldwide outage preventing users from posting messages, uploading images, or connecting to their servers.

When some users attempt to connect to Slack, they are greeted with errors stating, "Something's gone awry, and we're having trouble loading your workspace."

If you are still connected to your Slack server and try to post a message or upload an image, you will be greeted with a message stating, "Slack couldn't send this message Try again | Cancel," as shown below.

Slack is aware of the outage and is working on resolving them:

In our tests, reloading Slack did not fix the issues.

Update 5/20/21 2:57 PM EST: Slack has stated that they have resolved the issue and users can relaunch Slack to connect to their servers.

We've released a fix for this issue, and Slack is up and running once again. If you are still experiencing any trouble, please fully quit your Slack app or browser using Command + Q (Mac) or Ctrl + Q (Windows/Linux), and then reopen it.

Thank you very much for bearing with us on this, and if you're still encountering any trouble after a restart, let us know at feedback@slack.com.
