I'm posting a more optimistic thread with real answers (or the best they can determine) from SpaceX as to what caused the anomaly and the progress for a Return to Flight (RTF). First information from SpaceX on RTF: Peter B. de Selding on Twitter Peter B. de Selding@pbdes 2h2 hours ago SpaceX President Shotwell: We anticipate return to flight in November, meaning down for three months. Next flight from CCAFS, then to VAFB. So SpaceX is moving forward and will use Pad 39A and Vandenberg for launches until SLC-40 can be repaired. A further comment from Gwynne: Nov return to flight is our best hope. We still haven't isolated the cause or whether its origin was rocket or ground.
