Incident

Trouble loading channels

Issue Summary:

On 10 June, 2019 at 9:40 a.m. PDT, we deployed a version to our desktop app that caused a sudden increase in the number of connections to our servers. These connections were rate-limited by Slack’s servers in order to protect themselves. During this time, some customers were unable to load their workspaces, including channels and messages. We launched an investigation, but the system recovered soon after, allowing people to reconnect to Slack. At 10:56 a.m. PDT the issue was resolved.

We're happy to report that we're in the clear and everybody should be able to access their channels again. Sorry for the disruption, and thank you for bearing with us while we worked to fix things up.

Some folks may be having trouble loading their channels in Slack. We’re currently investigating and will have more information shortly. Thank you for your patience.
