Voted to adopt proposal 134553.
This proposal replaces 2 nodes, due to offboarding TO1 and AN1 data centres. Decentralisation parameters are unchanged and remain within the requirements of the target topology. Data centre details are consistent with the links provided in the proposal.
Vote: ADOPT
Replaces cordoned nodes 5d6pj and 77fe5 with nodes zxph7 and zk4lm on subnet nl6hn.
The reason for this proposal is to offboard TO1 and AN1 DCs consistent with forum posts made on the forum thread used for posts regarding the renovation/sell of Gen-1 node machines by NPs.
Both the NP and DC stated in the forum post match the ones from the node being removed in the proposal.
A new proposal with ID 135303 has been submitted, please take a look.
Motivation:
Calculated potential impact on subnet decentralization if replacing:
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,
and there are also instructions for performing what-if analysis if you are wondering if another node would have improved decentralization more.

VOTE: YES
TLDR: An offline node replaced with an unassigned node in the same country. Important decentralisation metrics remain unchanged, and the average distance between nodes is slightly improved.
Note that there’s 1 node country discrepancy for this subnet. The countries are close to one another, so the response latency approach employed by ipinfo.io may not be pinpointing location accurately enough (something to revisit…)
| Smallest Distance | Average Distance | Largest Distance | |
|---|---|---|---|
| EXISTING | 316.333 km | 7601.024 km | 16616.248 km |
| PROPOSED | 316.333 km | 7613.246 km (+0.2%) | 16616.248 km |
This proposal slightly increases decentralisation, considered purely in terms of geographic distance (and therefore there’s a slight theoretical increase in localised disaster resilience).

The above subnet information is illustrated below, followed by a node reference table:
Red marker represents a removed node (transparent center for overlap visibility)
Green marker represents an added node
Blue marker represents an unchanged node
Highlighted patches represent the country the above nodes sit within (red if the country is removed, green if added, otherwise grey)
Light grey markers with yellow borders are examples of unassigned nodes that would be viable candidates for joining the subnet according to formal decentralisation coefficients (so this proposal can be viewed in the context of alternative solutions that are not being used)
Black dotted line connects to a small black marker that shows where the IP address indicates the node is located (according to api.ip2location.io). This is only displayed if it conflicts with where IC records indicate the node is located. See Country Discrepancies section above for more info.

You may wish to follow the CO.DELTA known neuron (coming soon) if you found this analysis helpful.
We’re a verifiably decentralised collective who review IC deltas (changes applied by NNS proposals). We follow a common code:
Every vote cast by CO.DELTA is the result of consensus among diligent, skilled and experienced team members acting independently. The CO.DELTA neuron follows the vote of D-QUORUM on NNS topics that the CO.DELTA team does not handle directly. You can therefore follow CO.DELTA on all topics and rely on the highest quality of vote.
Note that this analysis involved data provided by the IC-API, which is not open source. I’m in the process of switching over to more verifiable sources of this sort of information for future proposal reviews. See here for related discussion.

Vote: Adopted
Reason:
The proposal replaces dead Offline status node u7niu from the JV1 DC in Florida, with unassigned healthy Awaiting status node k2dew from Dallas, without any change to decentralization.
