Proposal 135996 Review | Lorimer - CO.DELTA △
VOTE: YES
TLDR: The proposal ‘motivation’ claim below can be verified here, but running a text search on 4fedi-eu6ue-nd7ts-vnof5-hzg66-hgzl7-liy5n-3otyp-h7ipw-owycg-uae, showing that all nodes are currently allocated to subnets. This proposal removes one such node from this subnet.
We can see that the node provider for the replacement node (g2ax6-jrkmb-3zuh3-jibtb-q5xoq-njrgo-5utbc-j2o7g-zfq2w-yyhky-dqe) only has 3 of their 10 nodes assigned to subnets. This proposal increases that number to 4, balancing node provider allocation across subnets - making the IC Target Topology generally easier to achieve (less likely to get stuck in local optima).
Motivation: The node operator 4lbqo (under NP 4fedi) has 5 nodes in total and currently has all nodes assigned to subnets. We propose to remove one of the operator’s nodes from subnet pjljw to allow optimization of the overall network topology. The removal of the node from the subnet does not worsen subnet decentralization, and may allow the node to be assigned to subnet where it would improve decentralization.

The above subnet information is illustrated below, followed by a node reference table:
Map Description
-
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
ipinfo.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 if you found this analysis helpful.
CO.DELTA △
We’re a verifiably decentralised collective who review IC deltas (changes applied by NNS proposals). We follow a common code:
- Look: We observe the details and context of NNS proposals
- Test: We test and verify the claims made by those proposals
- Automate: We automate as much as possible by building increasingly sophisticated tools that streamline and strengthen the reviewal process.
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.
