The concert ticket provider Ticketmaster has apologized for the surprising stop in advance sales for the US stadium tour of superstar Taylor Swift (32). One is practiced in processing a large number of inquiries, it said in a statement on Saturday (local time).

However, the enormous demand and a “breathtaking number of bot attacks” led to a historic record of hits on the website.

Ticketmaster stopped presales on Thursday. “Due to exceptionally high demand on the ticketing systems and insufficient remaining inventory to meet demand, tomorrow’s public advance sale for Taylor Swift, The Eras Tour has been cancelled,” the company said.

Swift announced the tour in early November. The tour, titled “The Eras Tour,” will combine her ten studio albums to date, the musician announced. “A journey through the musical epochs of my career (in the past and present)” is planned. To mark the announcement, Swift shared a colorful graphic showing images of her from all of these eras – from country album Taylor Swift (2006) to recent pop concept album Midnights. It was not initially known when “The Eras Tour” would come to Europe.
