According to Leaseweb Security Officer Alex de Joode this quietness has also come about because the responsibility for dealing with cyber issues at Leaseweb has been transferred from the Dutch National Police to the regional authorities in a place called Kennemerland.
Leaseweb has also made progress in dealing with cybercrime issues across the board. Some of those are dealt with internally or with help of forensic and security companies rather than law enforcement authorities.
Leaseweb used to host parts of the MegaUpload infrastructure in the past and more recently it became known that it hosted pedo-file sharing service Oron.com.
