Sometimes I think some people just can't read and understand the content. OSG slow ring is something entirely different than Insider slow ring.
Build 10134 has a serious update bug so the can't release it to anyone outside their internal rings.
Fast ring will get build 10136 tomorrow or early next week (because they don't like to release new builds on friday but sometimes they do anyways). Slow ring will eventually get build 10136 sometime in the near future if it proves to be "slow ring worthy"
