Glastonbury Festival tickets have sold out in an hour but many fans were left frustrated after the booking site experienced a “technical problem”.

People complained that the site was repeatedly crashing at different stages of the booking process after the tickets went on sale at 9am on Sunday.

They usually sell out in around half an hour, but this year it took double the time.

Glastonbury’s official account posted at 10.03am: “Tickets for Glastonbury 2023 have now Sold Out.

“Thank you to everyone who bought one and we’re sorry to those of you who missed out, on a morning when demand far exceeded supply. There will be a resale of any cancelled or returned tickets in spring 2023.”

At 9.49am, See Tickets, the company running sales for Glastonbury, had asked fans to “bear with us” and said it was “working on a technical problem”.

Potential festival-goers vented their annoyance on social media.

One commented that it would be “easier to start a band and play Glastonbury than it is to get tickets”.

Another joked that “the clocks go back in October purely to give everyone an extra hour to waste trying for Glastonbury tickets”.

Tickets that include coach travel sold out in 23 minutes last week.

The 2023 festival takes place between 21 and 25 June 2023 at Worthy Farm in Somerset.

The price has increased to £335 plus a £5 booking fee, compared with £280 plus a £5 fee for the 2022 event.

Organiser Emily Eavis tweeted: “Although we are thrilled that so many of you want to come to next year’s Glastonbury, we’re sorry that a huge number of people missed out on a ticket this morning – because demanded far outstripped supply.

“Thank you for everyone who tried to buy a ticket. Your loyalty to this festival is deeply appreciated.

“There will be a ticket resale in spring 2023, so if you didn’t get one, please do try again then.”

Glastonbury finally celebrated its 50th year this summer after the coronavirus pandemic forced organisers to cancel twice.
