If you are one of those who are trying to buy a ticket for any concert by the American singer Tylor Swift, you should wait for the online ticket sales company, Ticketmaster, to allow your secure access. Late this Thursday, she reported that an avalanche of requests -3.5 million- collapsed the system to buy tickets through her digital sales portal.

The Eras Tour is the first tour in five years of the Pennsylvania singer and will tour the United States from coast to coast spread over 52 performances. That number makes it her biggest tour to date.

“Due to extraordinarily high demand for ticketing systems and insufficient inventory of remaining ticketing systems to meet that demand, tomorrow’s midnight public sale for Taylor Swift’s The Eras Tour has been cancelled.” Ticketmaster wrote this Thursday on its official Twitter page.

This situation caused complaints and more complaints from fans who could not purchase their precious ticket.

Given the bewilderment of the followers of the American singer, the company published a statement publicly apologizing for the technical problems. Assuring that the situation was “completely overwhelmed”, despite the fact that for the sale of tickets for Swift’s tour a special page had been enabled in which fans “had to register to avoid automatic purchases”.

The portal was blocked, this Thursday, after the registration of some 3.5 million users to have access to the purchase of tickets for their next tour. It represents the largest number of registrations, as reported by Ticketmaster in a press release.

Bots. This system of “verified -registered-followers” to avoid the presence of bots “failed”, could not satisfy the “unprecedented” high demand that, combined with the thousands of simultaneous requests from users, generated “traffic without unusual to its site, the company said.

On Tuesday, online ticket sales could not be completed due to the first avalanche of requests. “About 15% of the interactions on the site experienced problems,” he added that “about two million tickets” could be sold, the record for tickets sold online in a single day.

Following these incidents, Ticketmaster’s parent company, Live Nation Entertainment Inc, has not disclosed whether it is working to improve the technology to handle thousands of simultaneous requests and surges in demand. Before the despair of the followers of Tylor Swift.
