Proposal 135423 Review | Lorimer - CO.DELTA △

VOTE: Awaiting further discussion … YES (although really great points raised by @MalithHatananchchige! I’m interested to see further discussion on this, regarding confirmation on whether the DC’s are experiencing hardware or connectivity issues)

TLDR: Two down nodes replaced with two unassigned nodes at the same data centres. Decentralisation stats remain unchanged.

@MalithHatananchchige nice review! Particularly displaying the results of your automated checks :heart_on_fire: Regarding the ‘Awaiting’ status, my understanding was that this is an artificial status that the dashboard applies to indicate that the node is due to be added to a subnet (due to an open proposal). I could have the wrong end of the stick with that. If you check the raw status presented by the IC API both nodes have a status of ‘unassigned’ (I believe ‘down’ or ‘degraded’ would override an ‘unassigned’ status). I’ve never seen ‘awaiting’ in the raw status data, so I don’t think it actually represents a real node status (in terms of how it’s performing).

This is interesting. Perhaps there are multiple types of ‘awaiting’ status that are being conflated? I’ll hold off voting for now to aer on the side of caution, until there’s been some further discussion :slightly_smiling_face:

Country Discrepancies (4)

A few country discrepancies involving relatively small distances, so could be considered to be within a margin of error.

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.
