So basically this is saying that the CAP theorem is irrelevant because a partition is not really have a partition (since the load balancer still can reach everybody). Hmm...
I agree that in modern data centers the CAP theorem is essentially irrelevant for intra-DC services, due the uptime and redundancy of networking H/W (making a partition less likely than other systemic failures).
Across DCs I'll claim it is still absolutely relevant.
