On 6 October 2009, one of the IP transit providers to The Pirate Bay blocked all Pirate Bay traffic causing an outage for most users around the world. The same day, the site was reportedly back online at an IP address at CyberBunker, located in the Netherlands. It is not known whether The Pirate Bay is actually located at CyberBunker or whether they are using the CyberBunker service that routes CyberBunker IP addresses to any datacenter around the world. These routes are not visible to the outside world.
