On January 14, 2011, four major curling websites (CurlingZone, World Curling Tour, Ontario Curling Tour, and Canadian Curling Reporters) went offline in an apparent cyber attack by hackers from China and Korea. The problem was found to be missing databases of painstakingly documented curling information dating back two years from primary and secondary backup systems. For many weeks, the four websites and any content supported by CurlingZone's software were unable to be accessed. The proprietors of the websites were forced to request the help of data recovery services to recover the lost data, which includes information on thousands of curling events both major, like the Olympics season, and minor. As a result of these presumed cyber attacks, the websites were switched to a new server and reloaded with whatever information was available at the time.
Capital One, the sponsor of the Grand Slam of Curling, the World Curling Championships, and various teams and bonspiels, stated a few days after the incident that they would match donations to CurlingZone to help the recovery effort and encouraged other curling-related businesses to donate money. However, people involved with CurlingZone and The Curling News expressed concern that much of the data is irrecoverable and may have disappeared forever. As of March, the websites are up and running, but the content from last year and many years preceding it are still missing.
In another event, the websites of U.S. and world curling governing bodies were attacked by sites in China and Korea. The attacks may be related to the attacks on the four major curling websites.
The Dominion MA Cup presented by TSN was created for the first time for the 2010-11 season. The Cup is awarded to the Canadian Curling Association Member Association (MA) who has had the most success during the season in the CCA sanctioned events. Events include the Canadian Mixed, Men's & Women's Juniors, the Scotties, the Brier, Men's & Women's Seniors and the national Wheelchair championship.
