Connectivity issues affecting some workspaces

Technical Summary:

On October 23 at 4:23 PM PT we received an internal alert that some servers were overloaded due to unexpected traffic. As a result, some customers were unable to connect to Slack. As the servers recovered, we continued to investigate and monitor the issue. We called an all clear at 5:07 PM PT. We're investigating the root cause and making plans to ensure this doesn't happen in the future.

5:26 PM PST

We've been given the all-clear from the team. Everyone should be able to connect to their workspaces once more. But please let us know if not at feedback@slack.com. Apologies for this disruption to your day.

5:15 PM PST

No updates to share just yet on the connectivity issues though we're working to get you back in as quickly as possible.

5:06 PM PST

We're looking into reports of some people having trouble connecting to their workspaces. Apologies for this disruption.
