Highlights

Shipped: did we release anything this week?

• [ES/OS Migration] Completed migration from ES to OS in production https://phabricator.wikimedia.org/T388610
• [ES/OS DC Switch] Switching traffic by leveraging discovery DNS rather than config changes. More consistent with standard K8S setup, so it can be handled by service ops without knowledge of configuration changes. https://phabricator.wikimedia.org/T143553
• [CirrusSearch] Fixed issue with maintenance cron job https://phabricator.wikimedia.org/T395402
• [CirrusSearch/SUP] Consistent weighted tags https://phabricator.wikimedia.org/T393872
