Various instances going offline lately. Is there a place that lists the current status of major instances? - Lemmy.world

My other instance has been down for two days and I’m not sure where to go to see updates/discussion etc. After browsing this community I saw a few scattered posts reporting other instances going down. When Lemmy.World was down a week ago it was equally hard to find an explanation and/or a place to discuss what what happening. Is there a community or website dedicated to “instance x is down because y”?
