# Replace nodes in subnet lhg73

Motivation: 
 - replacing degraded node cilsw-jxcbi-qvp5o-7cylv-up5nj-2yykt-jtzha-s2uao-ee7uy-nprfm-vae
 - replacing dead node jfryc-owgdd-a7pp4-lao2c-anza2-nryvi-gqkmu-m2moj-4hzai-zfdiy-4qe

Calculated impact on subnet decentralization if replacing:



Based on the calculated impact, not replacing additional nodes to improve optimization.

Note: the information below is provided for your convenience. Please independently verify the decentralization changes rather than relying solely on this summary.
Here is [an explaination of how decentralization is currently calculated](https://dfinity.github.io/dre/decentralization.html), 
and there are also [instructions for performing what-if analysis](https://dfinity.github.io/dre/subnet-decentralization-whatif.html) if you are wondering if another node would have improved decentralization more.



Decentralization Nakamoto coefficient changes for subnet `lhg73-sax6z-2zank-6oer2-575lz-zgbxx-ptudx-5korm-fy7we-kh4hl-pqe`:
```
    node_provider: 5.00 -> 5.00    (+0%)
      data_center: 5.00 -> 5.00    (+0%)
data_center_owner: 5.00 -> 5.00    (+0%)
             area: 5.00 -> 5.00    (+0%)
          country: 5.00 -> 5.00    (+0%)
```

**Mean Nakamoto comparison:** 5.00 -> 5.00  (+0%)

Overall replacement impact: equal decentralization across all features

# Details


Nodes removed:
- `cilsw-jxcbi-qvp5o-7cylv-up5nj-2yykt-jtzha-s2uao-ee7uy-nprfm-vae` [health: degraded, impact on decentralization: (gets worse) the number of different NP actors decreases from 13 to 12]
- `jfryc-owgdd-a7pp4-lao2c-anza2-nryvi-gqkmu-m2moj-4hzai-zfdiy-4qe` [health: dead, impact on decentralization: (gets worse) the average log2 of Nakamoto Coefficients across all features decreases from 2.3219 to 2.0000]

Nodes added:
- `ffsue-5rmb7-frfqk-gvfpg-gu2bo-udoa3-zputb-kexzk-gd667-fit5k-rae` [health: healthy, impact on decentralization: (gets better) the average log2 of Nakamoto Coefficients across all features increases from 2.0000 to 2.3219]
- `7jjmd-p43kv-2h3bp-yrcuv-gc3ia-zaess-2rj6p-p4xgr-f43xy-6hk55-xqe` [health: healthy, impact on decentralization: (gets better) the number of different NP actors increases from 12 to 13]
