Bricklayer - New Data Center Evaluation "US: Los Angeles, California (DC2 AO) [USCA_2]"

Bricklayer has added the US: Los Angeles, California (DC2 AO) [USCA_2] data center, which is different from the original "US – Los Angeles DC2 QNET (USCA_2)". The new one is specifically pointed out. It is DC2 AO (this is Asia Optimization, the specific computer room is not mentioned), and the latter pointed out that it is a quadranet computer room. At present (August 2023), it is still not possible to directly place an order for this DC2 AO on the Bricklayer website. It is still the old quadranet computer room. This article takes everyone to take a look at the actual situation of the new DC2 AO. The test data is for reference only!

A rough summary:

Currently, the VPS hen should be under heavy load, and the overall performance is not that great;

In terms of network, all three network backhauls are directly connected back to China by operators from the West Coast. The routing optimization is quite good. I feel that this optimization is indeed very good.
