None I know about, or I'd warn or not advertise them in the first place. So, far I've read of them here on HN, about an year ago or so, signed up and everything is good so far. I don't know how they manage to offer storage at this price point, but I was quite surprised they had even lowered prices some months ago (10TB offer used to be ~10EUR and now the price's half of that). Either way, git-annex has redundancy. The stuff that's important to me is replicated across multiple storages, so even if one goes down it won't hurt much. And, sure, I advise everyone, whatever technology and storage provider(s) they use to have backup strategy and consider for failures.
