The optimisation and redistribution work brought error rates down, which resolved most of the issues with channel loading, group direct messages, hyperlinks, and Saved items that users were experiencing.Īt this point, we made the call not to re-enable the Threads view in order to give our recovery efforts more time to restore balance to the system. We also made several code changes to reduce the effect a de-provisioning job of this scale would have on our infrastructure, and redistributed some of the load across other parts of the system.
