We’d like to share an update regarding an upcoming node transition, and ensure full alignment with the community before moving forward.
Here’s what’s happening:
Decentralized Entities Foundation - DEF (a nonprofit foundation) is acquiring 8 node machines from Carbon12, an existing node provider.
Out of these 8 nodes, 4 are currently located in Paris, and DEF plans to relocate them to Barcelona. This move is motivated by:
Decentralization: Spain belongs to a different regional cluster than France/Switzerland/Germany, improving geographic distribution.
Cost efficiency: Barcelona offers more sustainable long-term hosting costs.
Important clarification on subnet handling:
Currently, 3 of the 4 Paris nodes are part of active subnets. DEF will not move these machines before coordination with the Dfinity Foundation.
Instead, we’ll first request subnet migration to existing, available DEF nodes already deployed in Barcelona.
Only after these subnet responsibilities have been moved will we proceed with the physical relocation of the hardware from Paris to Barcelona.
This ensures a seamless transition with no risk to network stability and improved decentralization.
About Carbon12’s departure:
While Carbon12 is stepping away from node operations, this transition ensures continuity. The machines remain in the ecosystem, operated by DEF – a foundation with no shareholders.
I’d like to confirm the information shared above by the @DEF regarding the transition of eight node machines currently operated by Carbon Twelve.
As outlined:
DEF will be taking over the operation of these nodes.
Four nodes are located in Paris (PR1) and are planned to be relocated to Barcelona (ES1), where another four nodes are already hosted.
Three of the four nodes in PR1 are currently active in subnets. These will remain in place until they have been removed from subnets.
Why This Matters:
Carbon Twelve (C12) is stepping back from node operations for the time being, but we remain committed to supporting the growth and evolution of the ICP ecosystem. This transition ensures continuity of operations and allows us to remain engaged with the IC ecosystem.
Next Steps:
Remove Active Nodes from Subnets: Hi @alexu, may I request that DFINITY take the necessary steps to remove all nodes belonging to C12 from their respective subnets to enable their offboarding. Let me know if anything is needed from my side to support this.
Registry Removal: Once all nodes are removed from subnets, I will remove them from the registry.
Node Operator Record Proposals: Two proposals will be submitted to remove the node operator records for PR1 and ES1.
Physical Migration: Nodes currently in PR1 will be de-racked, transported, and re-racked in ES1. DEF will take over onboarding responsibilities.
Although C12 is stepping away from operations for now, we remain committed to the Internet Computer and intend to return in the future. As such, I will not be submitting a proposal to remove the Node Provider principal. We acknowledge that the onboarding process may evolve and are fully prepared to comply with any updated requirements should we decide to rejoin.
Reason:
In line with the forum post from NP Carbon Twelve the 5 proposals remove 5 healthy online nodes that are in use for offboarding and and replace them with unassigned healthy Awaiting status nodes as follows:
for subnet uzr34 node xll74 from Antwerp, Belgium is added to replace C12 node atjbz from Paris, France.
for subnet x33ed node 3krwb from Chicago, US is added to replace C12 node oobdg from Paris, France.
for subnet pzp6e node 3krwb from Antwerp, Belgium, is added to replace C12 node pqcqa from Barcelona, Spain.
Additional node zzuq4 from Hong Kong is replaced by v27at from Argentina in order to improve decentralization.
for subnet tdb26 node 2nehn from Isle of Man is added to replace C12 node tgbmf from Paris, France.
for subnet x33ed node tsbrx from Geneva is added to replace C12 node pekym from Barcelona, Spain.
CodeGov has a team of developers who review and vote independently on the following proposal topics: IC-OS Version Election, Protocol Canister Management, Subnet Management, Node Admin, and Participant Management. The CodeGov NNS known neuron is configured to follow our reviewers on these technical topics. We also have a group of Followees who vote independently on the Governance and the SNS & Neuron’s Fund topics. We strive to be a credible and reliable Followee option that votes on every proposal and every proposal topic in the NNS. We also support decentralization of SNS projects such as WaterNeuron, KongSwap, and Alice with a known neuron and credible Followees.

Proposal 137088 Vote: Adopt
This proposal replaces 1 node in subnet uzr34, appearing in the decentralization tool as “UP” and owned by node provider Carbon Twelve, who is planning to hand over its nodes as announced in this post. As shown in the proposal, decentralisation parameters are slightly worsened with respect to country and remain within the requirements of the target topology.
Proposal 137089 Vote: Adopt
This proposal replaces 1 node in subnet x33ed, appearing in the decentralization tool as “UP” and owned by node provider Carbon Twelve. As shown in the proposal, community-agreed decentralisation parameters are unchanged and remain within the requirements of the target topology.
Proposal 137090 Vote: Adopt
This proposal replaces 1 node in subnet pzp6e, appearing in the decentralization tool as “UP” and owned by node provider Carbon Twelve, along with an additional node. As shown in the proposal, decentralisation parameters are slightly worsened with respect to country and remain within the requirements of the target topology.
Proposal 137091 Vote: Adopt
This proposal replaces 1 node in subnet tdb26, appearing in the decentralization tool as “UP” and owned by node provider Carbon Twelve. As shown in the proposal, decentralisation parameters are unchanged and remain within the requirements of the target topology, although noting that an identified node cluster has 2 nodes in this subnet both before and after the change.
Proposal 137092 Vote: Adopt
This proposal replaces 1 node in subnet bkfrj, appearing in the decentralization tool as “UP” and owned by node provider Carbon Twelve. As shown in the proposal, decentralisation parameters are worsened with respect to country but remain within the requirements of the target topology.
