The Canadian portion (shore end system) was laid off Nova Scotia by the Teleglobe cable ship CS John Cabot.

The country was however backed up by the second submarine cable, FARICE-1 The most notable effect of the event was a temporary shut-down of data communications by Iceland's universities and hospitals, which relied exclusively on CANTAT-3's services.

Although it was predicted that a full recovery of the cable would take ten days, starting from midnight on January 13, 2007, it actually took until July 29, 2007 before service was fully restored.

During that time, the Icelandic universities and hospitals in Akureyri and Reykjavík relied on emergency connectivity obtained via local internet providers Síminn and Vodafone.

Føroya Tele (Faroese Telecom) took over ownership and operation of the cable in 2012 to service oil platforms in the North Sea.
