We attempted to push the AMO 3.4.3 update last night but ran into some problems. Our initial investigation is pointing to the advanced search queries taking far longer than the previous version. The slave databases couldn’t handle the load and we had to back the update out. We’ll come up with a solution this weekend and plan on pushing the 3.4.3 update on June 12th.
AMO 3.4.3 delayed until June 12th
