I’ve been around here long enough not too expect much. Sometimes they do share some technical details, sometimes they just wave hands and brush it off. Truth is, these “incidents” have been happening quite regularly and will continue to happen. Several ST employees admitted that the platform is not designed to scale gracefully and the management is not up to the task to fix it. They’re just patching it here and there to limp along till the next “crisis”. 
P.S. One of the best explanations I’ve heard from one of ST staffers was “cloud flatulence”. I guess they’ve been feeding it too much chili.
