CANTAT-3 is the third Canadian transatlantic telephone cable, in operation from 1994, initially carrying 3 x 2.5 Gbit/s between Canada and Europe. It branches to both Iceland and the Faroe Islands.[citation needed]
On December 17, 2006, CANTAT-3 services were disrupted due to damage to the submarine cable, resulting in loss of service to hundreds of thousands of users connecting via internet and media providers (Síminn, Vodafone and Hive). The most notable effect of the event was a temporary shut-down of data-communications by Iceland's universities and hospitals which rely 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 it was fully restored. During that time the Icelandic universities and hospitals in Akureyri and Reykjavík relied on emergency connectivity obtained via local internet providers Siminn and Vodafone. The Icelandic government decided not to buy extra bandwidth for the university network through the functioning FARICE-1 cable, despite being a large shareholder in FARICE-1.[citation needed]
Landing points are:
- Pennant Point, Nova Scotia Canada
- Vestmannaeyjar, Iceland
- Tjørnuvík, Faroe Islands
- Redcar, England, UK
- Blaabjerg, Denmark
- Sylt, Germany
CANTAT-3 is operated by India's Teleglobe.
CANTAT-3 was the only NL-16[citation needed] laser regenerative 2.5 Gig/s submarine system built in the world. Part of this huge system was built at STC Submarine Networks, Portland, Oregon from 1993-1994 (which later became Alcatel Submarine Networks). STC Submarine Networks in Southampton, U.K. made the rest of the system. The Canadian portion (shore end system) was laid off Nova Scotia by the Teleglobe cable ship CS John Cabot. The main-lay portion was deployed off Nova Scotia towards the Faroes onboard the AT&T ship Global Mariner. Other cable ships were involved in the completion of this system. This was the northern most cable system ever deployed at the time.
