This is the tracking task for one of the Wikimedia Technology/Goals/2018-19 Q1.
Perform a datacenter switchover:
- Successfully switch backend traffic (MediaWiki, Swift, RESTBase, and Parsoid) to be served from codfw with no downtime and reduced read-only time.
- Serve the site from codfw for at least 3 weeks. Tentative dates are to switch over to codfw in the second half of September and switch back to eqiad after 3~4 weeks.
- Refactor the switchdc script into a more re-usable automation library and update it to the newer switchover requirements.
