TLDR: 1 offline node replaced with an unassigned node, and an additional node replaced in order to improve decentralisation metrics.
After this proposal there will be 1 node per country, improving decentralisation in this respect. It will also increase the number of continents, but at the expense of clustering nodes slightly more in Europe. However, continents are not a formal part of the IC Target Topology.
There’s a fairly large country discrepancy which I’ll plan to revisit at some point (it involves a node that isn’t directly affected by this proposal).

This proposal slightly reduces decentralisation, considered purely in terms of geographic distance (and therefore there’s a slight theoretical reduction in localised disaster resilience).

This proposal slightly improves decentralisation in terms of jurisdiction diversity.
Largest number of nodes with the same characteristic (e.g. continent, country, data center, etc.) →
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.

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.
This proposal replaces 1 node in subnet eq6en, appearing in the decentralization tool as “DOWN”, along with an additional node in order to improve overall topology. As shown in the proposal and verified using the DRE tool, decentralisation parameters are improved with respect to country and remain within the requirements of the target topology.
About CodeGov
CodeGov has a team of developers who review and vote independently on the following proposal topics: IC-OS Version Election, Protocol Canister Management, Subnet Management, Node Admin, and Participant Management. The CodeGov NNS known neuron is configured to follow our reviewers on these technical topics. We also have a group of Followees who vote independently on the Governance and the SNS & Neurons’ Fund topics. We strive to be a credible and reliable Followee option that votes on every proposal and every proposal topic in the NNS. We also support decentralisation of SNS projects such as WaterNeuron, KongSwap, and Alice with a known neuron and credible Followees.

The proposal replaces one offline node in HongKong (Asia) and one healthy node in Orlando (North America). This helps to recover offline node and increases decentralization.
Warning
Proposed DC Bucharest seems to be congested with more than 80% of nodes on subnet, It would be good if the @DRE-Team could distribute future offline nodes to other DC with similar decentralization stats. However, I vote to ADOPT

Vote: Adopted Reason:
The proposal replaces 2 nodes: one dead Offline status node s5waw from the HK4 DC in Hong Kong,
and one healthy additional node to improve optimization, gta2q from the OR1 DC in Florida,
with unassigned healthy Awaiting status node 7jxpa from Africa and unassigned healthy Awaiting status node 5hqad from Romania, with slight improvement to decentralization.

dead node s5wawDashboard Status: Active and dead node gta2qDashboard Status: Active
with nodes:
node 7jxpaDashboard Status: Awaiting and node 5hqadDashboard Status: Awaiting
Although at the time of this post the dead nodes show in the dashboard as Active, it can be seen through the Node Provider Rewards for 7jxpa and Node Provider Rewards for gta2q that this nodes have been having inconsistent behaviour through the past 5 days.
The node gta2q replacement also improved the country coefficient, reducing the number of nodes in the US from 2 to 1.
