Replace nodes in subnet gmq5v

Motivation:
The following nodes in subnet gmq5v have been cordoned and need to be removed from the subnet:

Decentralization Nakamoto coefficient changes for subnet gmq5v-hbozq-uui6y-o55wc-ihop3-562wb-3qspg-nnijg-npqp5-he3cj-3ae:

    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

Proposal 134547

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

Decentralisation Stats

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

Smallest Distance Average Distance Largest Distance
EXISTING 477.324 km 7545.121 km 16759.085 km
PROPOSED 476.502 km (-0.2%) 7576.275 km (+0.4%) 16759.085 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). :+1:

Subnet characteristic counts →

Continents Countries Data Centers Owners Node Providers Node Operator
EXISTING 4 13 13 13 13 13
PROPOSED 4 13 13 13 13 13

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)

You may wish to follow D-QUORUM if you found this analysis helpful.

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.

Voted to adopt proposal #134547.

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.

Voted to adopt proposal 134547.

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.

Proposal 134547

Vote: ADOPT

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.
