Send traffic to new maps200? servers
Closed, ResolvedPublic


It seems that we have a LVS instance for kartotherian (kartotherian.svc.codfw.wmnet) between varnish servers and maps servers. We need to add new servers to its configuration.

Note: I'm still not entirely confident I understand everything around our caching / traffic routing, I might be completely wrong here....
