The organisers of July's Commonwealth Games in Glasgow have closed the ticket website and phoneline due to an ongoing fiasco with sales.
Glasgow 2014 says the measure was necessary to address technical issues which had hampered the sales of a hundred thousand extra tickets since Monday.
So far, about 55,000 of the extra tickets have been bought with diving, swimming, mountain biking, track cycling and the triathlon all sold out.
Extra tickets for all 17 sports and the opening and closing ceremonies went on sale on a first-come, first-served basis on Monday.
It quickly became apparent from comments posted on social media sites that the online site could not cope with demand.
Some people said they been trying to get tickets for up to 24 hours. People also reported problems with the phone booking system.
