Subnet Management - 5kdm2 (Application)

[ZackDS]

Proposal #135840 — Zack | CodeGov

Vote: Adopted

Reason:
The proposal replaces dead Degraded status node fpjx3 from Hong Kong with
unassigned healthy Awaiting status node tkdjq from Hong Kong4 without any change to decentralization.

VOTE: YES

TLDR: Degraded node replaced with an unassigned node. Decentralisation coefficients are unchanged - LGTM.

A new proposal with ID 136575 has been submitted, please take a look.

Click here to open proposal details

Replace a node in subnet 5kdm2

Motivation:

• replacing cordoned node tkdjq (freeing up nodes from Web3game in order to update ipv6)

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

Proposal 136575 Review | Lorimer - CO.DELTA △

VOTE: NO

TLDR: The proposal does not provide reference to sufficient evidence in order to verify/confirm its claim.

@Lorimer

This is a requirement that has been brought up as necessary time and again. I do not wish for proposals like this to continue being normalised. Nudging nodes in and out of subnets is an operation that carries significant security implications, and all the supporting evidence/justification for the swap should be provided in the proposal summary (it’s not something voters should be expected to have to hunt for).

Country Discrepancies (1)

@Lorimer

@alexu, can I ask where RIPE Atlas locates this node? I’ve not yet set myself up on the network, so don’t have any credits in order to check. I also noticed that my prior checks on an earlier discussion using ipinfo.io may have been inaccurate simply due to a stale local cache that I was using. I’ve just cleared it out and these are the results I’m getting for this node at the moment. Curious to see how that matches up with what you get.

PROPOSED	479.703 km	8297.874 km (-2.1%)	16348.372 km

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

• 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.

Proposal 136575 – LaCosta | CodeGov

Vote: ADOPT

The proposal replaces a cordoned node on subnet 5kdm2:

• removes cordoned node tkdjq Dashboard Status: Active.
• adds node uouxk Dashboard Status: Awaiting.

There is no impact in the decentralization metrics.

As explained in this post and verified by the NP here the cordoned node is being removed in order to redeploy it due to getting new IPv4 and IPv6 ranges.
