# Replace nodes in subnet uzr34

Motivation: 
 - replacing ham46-r7u4j-yoyrk-mrnxu-utzq3-c37he-vcns2-gc5yg-jxyv5-mvlhc-gae as per user request: aligning subnet decentralization with the target topology
 - replacing v6caw-kf4b4-j22f5-pqsvj-hg7dj-wx4xx-y7urh-eixmh-hnvz7-hoe2v-jae as per user request: aligning subnet decentralization with the target topology
 - replacing ysjs7-fe67q-k7pxe-g4puk-d5z7p-xrtg2-xqcmy-pmpoa-7bcfu-pmlqy-rae as per user request: aligning subnet decentralization with the target topology
 - replacing os2wv-dchv6-fjwdg-nichf-3cra6-wccb3-57glq-xqgen-zwobp-aonve-lqe as per user request: aligning subnet decentralization with the target topology

NOTE: The information below is provided for your convenience. Please independently verify the decentralization changes rather than relying solely on this summary.
Code for calculating replacements is at https://github.com/dfinity/dre/blob/79066127f58c852eaf4adda11610e815a426878c/rs/decentralization/src/network.rs#L912

Decentralization Nakamoto coefficient changes for subnet `uzr34-akd3s-xrdag-3ql62-ocgoh-ld2ao-tamcv-54e7j-krwgb-2gm4z-oqe`:
```
  node_provider: 10.00 -> 10.00    (+0%)
    data_center: 10.00 -> 10.00    (+0%)
data_center_owner: 8.00 -> 10.00   (+25%)
           city: 10.00 -> 10.00    (+0%)
          country: 5.00 -> 6.00   (+20%)
        continent: 2.00 -> 2.00    (+0%)
```

**Mean Nakamoto comparison:** 7.50 -> 8.00  (+7%)

Overall replacement impact: (gets better) the average log2 of Nakamoto Coefficients across all features increases from 2.7146 to 2.8121
