I saw our Norwegian subdomain take a bit of a hit at the beginning of the month. We dropped from positions three and five to ninety five and ninety eight for two of our main phrases. We then removed all the links from two IPs that linked to us extensively.
Checked again yesterday and they are right back to where they were before. We even improved rankings on a couple of other phrases too.
