Some disgruntled customers this morning took to Twitter to voice their dissatisfaction with the organisers of London 2012 over ticket sales.
One tweeted: "Glad I didn't want any Olympic Tickets seems like another shambles by Locog. Hope the events are organised better than this."
Another Tweet said: "Locog has done brill job creating ticketing panic."
Due to the high-level of demand, Locog was forced to temporarily block the website, at 6am, to new entrants for 15 minutes. However, it was fully operational afterwards.
A spokesman for Locog responded to public concern by saying "Olympics ticketing process this morning is like the Tube in the morning. Too many people and some have to stay on the platform."
But one expert believes Locog should have been prepared for the high-level of demand.
Michael Allen, director of IT service management at Compuware, the website performance specialist said: "If the organisers ran tests to check the site's ability to handle traffic ahead of the tickets going on sale for the second time, they would have picked up on any potential problems."
Around 2.3 million tickets will be on sale for 10 days on a first-come-first-served basis.
Tickets will be available for sports including fencing, basketball and archery.
