Subnet Management - 5kdm2 (Application)

[timk11]

Voted to adopt proposal 134272. The proposal seeks to remove a cordoned node from the subnet and specifies that the associated data centre is being offboarded “after 48 months”. Decentralisation parameters are unchanged. The necessary context is provided by this forum post and associated discussion. For future proposals of this type I recommend that the background context be included in the proposal text for ease of verification.

[Lorimer]

I’ve voted to reject proposal 134272. It makes claims that I see no clear way of verifying, and supporting statements regarding the ownership of the data centre are inconsistent with records held in the IC registry. The proposal was announced here.

[LaCosta]

Voted to adopt proposal 134272. This proposal is part of a sequence of steps to remove cordoned nodes from subnets as the associated data centeres are being offboarded after 48 months of their respective DC contracts that are still private and were signed up before the Genesis. There is a great and detailed explanation of this changes in this forum post and the forum thread it is in. In the wiki there is a series of Steps for Gen-1 Node onboarding after 48 months that need to be followed in order for the nodes to continue earning rewards which starts by making a forum post in the following thread. As we can verify no one as come forward with nodes from the DCs in this proposals so I don’t see any issues with the removal of this nodes.

Replace a node in subnet 5kdm2

Motivation:
The following nodes in subnet 5kdm2 have been cordoned and need to be removed from the subnet:

• tybza: offboarding the second rack of nodes in the GE1 DC after 48 months; Proposal: Update Interim Gen-1 Node Provider Remuneration After 48 months - #148 by Gwojda and Proposal: Update Interim Gen-1 Node Provider Remuneration After 48 months - #150 by katiep

Decentralization Nakamoto coefficient changes for subnet 5kdm2-62fc6-fwnja-hutkz-ycsnm-4z33i-woh43-4cenu-ev7mi-gii6t-4ae:

    node_provider: 5.00 -> 5.00    (+0%)
      data_center: 5.00 -> 5.00    (+0%)
data_center_owner: 5.00 -> 5.00    (+0%)
             area: 5.00 -> 5.00    (+0%)
          country: 4.00 -> 5.00   (+25%)

Mean Nakamoto comparison: 4.83 → 5.00 (+3%)

Overall replacement impact: (gets better) the average log2 of Nakamoto Coefficients across all features increases from 2.2683 to 2.3219

Proposal 134908 Review | LORIMER Known Neuron

VOTE: YES

TLDR: Improves decentralisation stats and there is a clear public declaration for the cordoned node which is referred to in the proposal summary.

1 removed nodes replaced with a healthy node in Canada.

Decentralisation Stats

Subnet node distance stats (distance between any 2 nodes in the subnet) →

	Smallest Distance	Average Distance	Largest Distance
EXISTING	0 km	6521.951 km	15377.131 km
PROPOSED	476.502 km (+∞%)	7130.87 km (+9.3%)	15377.131 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).

Subnet characteristic counts →

	Continents	Countries	Data Centers	Owners	Node Providers	Node Operator
EXISTING	4	12	13	13	13	13
PROPOSED	4	13 (+7.7%)	13	13	13	13

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.) →

	Continent	Country	Data Center	Owner	Node Provider	Node Operator
EXISTING	7	2	1	1	1	1
PROPOSED	6 (-14.29%)	1 (-50%)	1	1	1	1

See here for acceptable limits → Motion 132136

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)
• WaterNeuron (the WaterNeuron DAO frequently discuss proposals like this in order to vote responsibly based on DAO consensus)

Proposal #134908 — Zack | CodeGov

Vote: Adopted
Reason:
The proposal replaces cordoned healthy Active status node tybza from Geneva, with
unassigned healthy Awaiting status node 62yzt from Toronto, this improves the decentralization of the subnet.
The motivation makes sense and the provided Forum link included in the summary provides further info.

Proposal 134908 – LaCosta | CodeGov

Vote: ADOPT

Replaces cordoned node tybza with node 62yzt on subnet 5kdm2.
The reason for this proposal is to offboard the GE1 DC 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.

Updating the list of public subnets

Proposal 134924 Review | LORIMER Known Neuron VOTE: YES TLDR: Makes 5kdm2 public (for anyone to deploy canisters to). It’s currently private, with explicit deployment privileges available to a select few principals. I’ve checked the claims in the proposal against CMC data and proposal history, and have produced the table below. From what I can see the claims in the proposal are accurate. As with previous proposals there are numerous principals with privileged deployment access to this private…

Replace nodes in subnet 5kdm2

Motivation:

• replacing dead node lk2ji
• replacing dead node uao44

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.

Decentralization Nakamoto coefficient changes for subnet 5kdm2-62fc6-fwnja-hutkz-ycsnm-4z33i-woh43-4cenu-ev7mi-gii6t-4ae:

TLDR: 2 offline nodes replaced with 2 unassigned nodes. Average distance between nodes increases, as well as the number of continents.

There’s an interesting country discrepancy that may be worth revisiting, but it doesn’t involve a node that’s affected by this proposal.

Country Discrepancies (1)

Node	Data Center	Claimed Country	According to ipinfo.io
62yzt	Toronto 2	Canada	United States of America (the)

Decentralisation Stats

Subnet node distance stats (distance between any 2 nodes in the subnet) →

	Smallest Distance	Average Distance	Largest Distance
EXISTING	468.191 km	7433.905 km	15362.693 km
PROPOSED	479.703 km (+2.5%)	8476.533 km (+14%)	16348.372 km (+6.4%)

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

Subnet characteristic counts →

	Continents	Countries	Data Centers	Owners	Node Providers	Node Operator
EXISTING	4	13	13	13	13	13
PROPOSED	5 (+20%)	13	13	13	13	13

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.) →

	Continent	Country	Data Center	Owner	Node Provider	Node Operator
EXISTING	5	1	1	1	1	1
PROPOSED	5	1	1	1	1	1

See here for acceptable limits → Motion 132136

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.

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.

Proposal 135413 – LaCosta | CodeGov

Vote: ADOPT

The proposal replaces two dead nodes on subnet 5kdm2:

• dead node lk2ji Dashboard Status: Offline and dead node uao44 Dashboard Status: Offline

with nodes:

• node haeka Dashboard Status: Awaiting and node tu7cd Dashboard Status: Awaiting

All the nodes from the DCs of the replacement nodes look healthy so no concerns should arise from this replacement.

There is no impact in the overall decentralization across all features.

A new proposal with ID 135840 has been submitted, please take a look.

Click here to open proposal details

Replace a node in subnet 5kdm2

Motivation:

• replacing degraded node fpjx3

Calculated potential impact on subnet decentralization if replacing:

• 1 additional node would result in: equal decentralization across all features

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.

Decentralization Nakamoto coefficient changes for subnet 5kdm2-62fc6-fwnja-hutkz-ycsnm-4z33i-woh43-4cenu-ev7mi-gii6t-4ae:

    node_provider: 5.00 -> 5.00    (+0%)
      data_center: 5.00 -> 5.00    (+0%)
data_center_owner: 5.00 -> 5.00    (+0%)
             area: 5.00 -> 5.00    (+0%)
          country: 5.00 -> 5.00    (+0%)

Mean Nakamoto comparison: 5.00 → 5.00 (+0%)

Overall replacement impact: equal decentralization across all features
