# Replace a node in subnet e66qm

Motivation: 
 - replacing dead node l2bzb-vpnu6-jlsae-poddg-5hpnz-bx54x-3khc2-aazpn-bop4m-zforf-uqe

Calculated potential impact on subnet decentralization if replacing:

- 1 additional node: equal decentralization across all features

Based on the calculated potential 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 `e66qm-3cydn-nkf4i-ml4rb-4ro6o-srm5s-x5hwq-hnprz-3meqp-s7vks-5qe`:
```
    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:
- `l2bzb-vpnu6-jlsae-poddg-5hpnz-bx54x-3khc2-aazpn-bop4m-zforf-uqe` [health: dead, impact on decentralization: (gets worse) the number of different NP actors decreases from 13 to 12]

Nodes added:
- `o2q5i-kszma-radgr-fdzu5-iqfps-w6xfc-aka7m-fftq4-2lpar-wj6xc-mqe` [health: healthy, impact on decentralization: (gets better) the number of different NP actors increases from 12 to 13]
