hmmm.. happened here after we were open only a week or so, having moved the 8 month old site from a host who required us to use banner ads to be hosted there. No one claimed the honors, but I am pretty sure it was the previous hosting company. We started over with backups ~3 months old. Took us lots of work to put it back together but we grew stronger than ever since then.
Recent backups are a must and should be on everyone's mind as part of the required site administration.
