People should be worried about stuff like this. Banetele is a facilities-based network operator in Norway and these guys are directly attacking their BGP sessions to put them off the air.

Can anyone from Banetele/who knows Banetele confirm this attack took place?

According to the people I spoke to, they had not noticed such an attack on the date specified. Steinar Haug, Nethelp consulting, sthaug@nethelp.no (who used to work for BaneTele, and was intimately involved with getting suitable BGP filters in place)
