I just launched a very modest blog on Sunday called ItDied (at ItDied.com, naturally). The idea of the blog is to track hosting services as they go under. There are a lot failing all of a sudden and many, many more to come. In some cases, this might be a photo service that gives its customers 24 hours' notice about their business shutting down (true!); in another, it could be Google providing 3 months' notice of a change (also true).I didn't find anyone tracking these shutdowns, where your "cloud"-stored data might evaporate as the sunshine of a bad economy comes out (or some horrible metaphor like that). I'll try to provide references for people where there's a reasonable place to migrate data, if such a place exists, too.
