Proposal 135411 Review | Lorimer - CO.DELTA △
VOTE: I’ll consider and vote tomorrow… YES (but follow-up proposal needed, due to the degraded node)
TLDR: 2 offline nodes replaced with 1 up unassigned node and 1 degraded unassigned node. I would consider rejecting this due to the degrade node being brought into the subnet, but given that the two nodes being replaced are even worse (they’re offline) this proposal is an improvement.
IC Target Topology metrics remain unchanged by this proposal. There are some country discrepancies, but involving nodes that are unaffected by the proposal (something to revisit).

Decentralisation Stats
Subnet node distance stats (distance between any 2 nodes in the subnet) →
| Smallest Distance | Average Distance | Largest Distance | |
|---|---|---|---|
| EXISTING | 9.63 km | 7870.256 km | 19461.421 km |
| PROPOSED | 9.63 km | 7935.417 km (+0.8%) | 19461.421 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 →

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.

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.
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.
