If it can be a beginning of an answer: the rendering process does seem to be rather slow, and has been for a couple of weeks in my observation. But I have no indication that any service should be down, at the contrary I find everything working as usual - even if, sometimes somewhat slower. For a free service, that is nothing to complain about, at the contrary.
For more precise answers it will indeed be required to ask more specific questions.
What exactly are you trying to achieve, and what are your actions?
