Aren't the Leaseweb servers just a mirror of the US servers? Being an international hoster it wouldn't make much sense to host individual files on just one server.
Also while this sure sucks for people who had files hosted there what was Leaseweb supposed to do? Can't really fault them for wiping servers that nobody paid for. Also this prevents them getting dragged into any legal proceedings like when the proscuter decides he needs more data for his case.
