Now that the maps eqiad cluster is ready, it is time to actually send traffic there after some validation that this cluster is working correctly.
This requires at least:
- adding the kartotherian eqiad as a backend to varnish
- changing cache routing to eqiad -> direct and codf -> eqiad (this needs to be done in 2 separate commits)
- since tile generation is more recent on eqiad, we might need a full cache purge to ensure coherence of tiles (@Yurik can you confirm?)
@BBlack : I'm probably missing steps in the above plan, could you check?
