This topic is intended to capture Subnet Management activities over time for the mkbc3 subnet, providing a place to ask questions and make observations about the management of this subnet.
The proposal leads to further clustering within Europe and a reduction in the average distance between nodes, but the resulting topology is within the IC Target Topology specification.

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

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)

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 node asad5 which appears in the dashboard as “Degraded”. As seen in the Node Provider Rewards tool, the node has had a high failure rate (around 13-16%) over the last several days for which data are recorded.
The replacement node appears in the dashboard as “Healthy”. As shown in the proposal, decentralisation parameters are unchanged 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, API Boundary API Boundary Node 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.

Reason:
Replaces Degraded node with IC_Replica_SlowerServerThanSubnetMedian status asad5 from TY1 DC in Tokyo with healthy unassigned node bs7jr from Frankfurt, without any change to decentralization.

TLDR:
This proposal removes 1 node(s) from Tokyo and adds 1 replacement node(s) in Frankfurt 2.
The degrade node seems to be having major connectivity issue causing for blocks to miss. Decentralisation stats remain the same, vote to adopt

Summary:
The replaced node is flagged as Degraded with a status of IC_Replica_SlowerServerThanSubnetMedian. Looking at the Node Provider Rewards we can see that this node is averaging a 16% failure rate. This is indeed not optimal performance and so the node should be replaced.
The proposal replaces one degraded node on subnet mkbc3:
Added Nodes: nodes bs7jr, Dashboard Status: Healthy and Not assigned to a subnet
The decentralization remains unchanged across all features
The subnet is within the current approved IC Target Topology so no issues here.
