Now that the Anycast RecDNS service is up and running with live traffic, we can progressively make more servers use it in their resolv.conf.
Rollout status update: things that are using anycast recdns resolv.conf in production as of 2019-07-31:
- All hosts in edge DCs (esams, ulsfo, eqsin)
- All cp edge cache hosts globally
- All LVS hosts globally
- Canary Mediawiki API and Appserver hosts in both core DCs
- Network devices
- Install-time stuff (as in dhcp settings and Debian installer)
