How Discord Scaled Elixir to 5,000,000 Concurrent Users

Super interesting article! In the “Fast Access Shared Data” topic, I am confused about this statement: “This noticeably improved performance, but ETS reads were about 7μs, and we were still spending 17.5 seconds on looking up values in the ring.” I can’t figure out why it takes 17.5 seconds to look up a value in the ring? Is it because ETS is not distributed?
