Connectivity issues affecting some workspaces in South America

Technical Summary:
On September 7th between 7:43am PT and 8:05am PT, Slack could not connect to our servers in the Sao Paulo region due to network issues. As a result, some people could not access their workspaces.

At 8:05am PT we deployed a fix that would route users out of the troubled region and to a healthier server, which allowed people to successfully connect to Slack again.

We are currently hard at work on scoping preventive measures to ensure this doesn’t happen in the future.

6:23 PM PST

We've patched up the connectivity issues for the South America folks, and things should be working better now with a refresh (CMD/CTRL + R). If this isn't the case, don't hesitate to drop us a line and let us know.

8:23 AM PST

We've confirmed that folks are running into issues when trying to connect from South America specifically. We're looking into this further, and will keep updating with new information.
