# Replace a node in subnet gmq5v

Motivation: The following nodes in subnet `gmq5v` have been cordoned and will be removed:
- dtw2y: offboarding SJ1 DC after 48 months

Decentralization Nakamoto coefficient changes for subnet `gmq5v-hbozq-uui6y-o55wc-ihop3-562wb-3qspg-nnijg-npqp5-he3cj-3ae`:
```
    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: 3.00 -> 4.00   (+33%)
```

**Mean Nakamoto comparison:** 4.60 -> 4.80  (+4%)

Overall replacement impact: (gets better) the average log2 of Nakamoto Coefficients across all features increases from 2.1745 to 2.2575
