Incident

Connectivity issues in Europe

Technical Summary:
From 12:27am to 01:50am PT, people in Europe were not able to access Slack.

Networking problems caused our servers in central Europe to be unreachable to Slack clients, resulting in people being unable to connect. We diverted traffic away from this region to other facilities in Europe, which allowed people to reconnect to Slack once again. An all clear was called at 01:50am PT.
