Some users may be experiencing connectivity issues.

On Tuesday November 29th from 10:32am PST to 2:07pm PST, customers in some regions began noticing connection issue with Slack.

An automation from an upstream DNS service accidentally blocked slack.com queries in a limited region (mostly the Northeast US).

After communication with the upstream provider, the issue was identified and corrected. Impacted users should have no further issues connecting to Slack.
