• let the team know in the #post-outage-actions Slack channel and ask any clarifying questions

2. Publish incident report

• open a PR in https://github.com/2i2c-org/incident-reports if you're happy with the resolution
• or ask another team member to do it via the #post-outage-actions Slack channel
