What are all the current points of centralization for the IC?

[Jesse]

I hear often that the boundary nodes are a major point of centralization for the IC. I’ve witnessed firsthand the effects that one faulty boundary node had on the entire network.
Months ago, one boundary node went down and it left a large portion of IC users unable to access any app built on the ic for the entire time that the node was down. I’m curious if there are any more key infrastructures that are also centralized (as in the case of the boundary node infrastructure) and where is the progress being tracked with regard to decentralizing these infrastructures?

Boundary Node Roadmap

The boundary nodes are the gateway to the Internet Computer (IC), which allow users to seamlessly access the canister smart contracts running on it: through stock browsers users are served web-content fully from the chain. To this end, the boundary nodes translate the users’ requests into API canister calls, route these calls to the subnet running the canister and load balance among the subnet’s replica nodes. In addition, boundary nodes provide caching and other services for improved performanc…

Long Term R&D: Boundary Nodes (proposal)

1. Summary This is a motion proposal for the long-term R&D of the DFINITY Foundation, as part of the follow-up to this post: Motion Proposals on Long Term R&D Plans (Please read this post for context). This project’s objective The boundary nodes are the gateways to the IC. Their main purpose is to translate HTTP requests from users into calls to canister smart contracts on the IC and route calls to nodes on the corresponding subnet. In addition, boundary nodes provide load balancing, caching,…
