Adjusting Target Topology for Caffeine Scaling: 60 application subnets and a US subnet

Proposal 137235 Review | Lorimer :infinity: :dog_face: - CO.DELTA △

VOTE: NO

TLDR: This is a proposal to create the new US subnet described in IC Target Topology Proposal 137147. Unfortunately the parameters of this subnet creation proposal do not conform to the elected target topology (see ‘Decentralisation Stats’ below).

As specified, there should be no more than one node in this subnet that is owned by the same DC provider. Tierpoint, Flexential and Datasite would each own 2 nodes in this subnet if it passes. The IC Target Topology is unachievable with respect to the US subnet, as pointed out by timk11. Here’s the full list of DC owners with DCs in the US

  • CyrusOne: 70 replica nodes, 0 other nodes
  • Datasite: 53 replica nodes, 3 other nodes
  • Digital Realty: 41 replica nodes, 1 other nodes
  • Evocative: 28 replica nodes, 0 other nodes
  • FiberState: 3 replica nodes, 0 other nodes
  • Flexential: 69 replica nodes, 1 other nodes
  • Hurricane Electric: 3 replica nodes, 0 other nodes
  • InfoObjects: 4 replica nodes, 0 other nodes
  • Tierpoint: 56 replica nodes, 0 other nodes
  • TRG: 13 replica nodes, 1 other nodes

There are only 10 DC owners, and therefore not enough to support a 13 node subnet.

Either the IC Target Topology will need reformulating, or more DCs will need onboarding before creating the US subnet in a way that is compliant.

You may wish to follow the CO.DELTA known neuron 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.
