Hello. If you have specific issues that needed to be address, it is best if you can create a separate topic and complete the template so someone can take a look at it. Judging on the recent posts here, there are others experiencing this as well. Based on my estimate this happened in the evening and before midnight (GMT) at least one reported having their site back already. If these issues are related, then this is just a temporary hiccup. It is unfortunate it happened in unholy hours.
Also note that there are recent changes (around this same time) in the File Manager to improve user experience, so this might be one of those down times.
In any event that the suspension you have is from a completely different reason, you can check My account is suspended, what can I do now
