TLDR: I’ll adopt. The proposal links directly to what appears to be discussion with the NP about the proposal. Decentralisation stats look good.

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:
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)

Known Neurons to follow if you're too busy to keep on top of things like this
If you found this analysis helpful and would like to follow the vote of the LORIMER known neuron in the future, consider configuring LORIMER as a followee for the Subnet Management topic.
Additional good neurons to follow:
D-QUORUM (a highly decentralized neuron that follows neurons that have been elected by the NNS)
Synapse (currently follows the LORIMER and CodeGov known neurons for Subnet Management, and is a generally well informed known neuron to follow on numerous other topics)
CodeGov (actively reviews and votes on Subnet Management proposals, and is well informed on numerous other technical topics)
WaterNeuron (the WaterNeuron DAO frequently discuss proposals like this in order to vote responsibly based on DAO consensus)
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.
The proposal replaces two cordoned healthy Active status node 6rib4 from the SG3 Data Center in Singapore, and cordoned healthy Active status node mtca7 from the TO1 Data Center in Toronto, with unassigned healthy Awaiting status node dpxqr from Toronto 2 and with unassigned healthy Awaiting status node f63hs from Singapore 1, without any change to the decentralization of the subnet.
The motivation makes sense and the provided Forum link included in the summary provides further info, also it can be checked here.
This proposal replaces 2 nodes, due to offboarding SG3 and TO1 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.
Replaces cordoned nodes 6rib4 and mtca7 with nodes dpxqr and f63hs on subnet gmq5v.
The reason for this proposal is to offboard TO1 and SG3 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.
This proposal replaces 1 node in subnet gmq5v, appearing in the decentralization tool as “DOWN”. 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, 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.

TLDR: One offline node replaced with an unassigned node. IC Target Topology metrics remain unchanged, but the average distance between nodes increases slightly.
Country Discrepancies (2)
There a relatively large country discrepancy (in terms of distance). Given that ipinfo.io uses a probe network for geolocation, I’m surprised to see such a large discrepancy. Something to revisit (given that the node in question isn’t directly affected by this proposal).

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 (coming soon) 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.

TLDR:
The proposal replaces offline nodes in Allentown (North America).
The decentralization stats remain the same.
Warning
The last few proposals that address the outage of DC is offloading all nodes to one Node provider. @DRE-Team Is there a way we can address this issue in the future to offload nodes into multiple Node providers. I will vote to Adopt to recover this issue in hopes that this feature will be addressed.
Node 6b667…: Health check passed. Node 6b667…: Remove from Subnet check passed. Node ochxw…: Replacement Status check passed.
