Officials at Neste Corp. said base oil production at the companys refinery in Porvoo, Finland, was not affected by a major disruption in the companys internet technology systems. Neste reported Monday that the problem interrupted activities in Finland and the Baltic region, but a spokesperson said this morning that production at the API Group III base oil plant in Porvoo will continue normally. Neste said the problem stemmed from a hardware failure in a data center of its service provider.
