This year would have been my 8th Glastonbury since 2007, tips for getting tickets, well get in a group with 3 or 4 other people, each have a laptop on a different internet connection, have chrome/edge/safari/firefox each with 1 tab open, have all your details ready to enter in case you get through, keep pressing F5 until you see the payment screen/sold out screen, pray to God/Allah/L Ron Hubbard/David Bowie/Michael Eavis and hope for the best
You need to be prepared, don't think you can just wake up at 9:30 on ticket day and think you'll just get on the web page and go straight to the payment page
