My tracker checks once every 5 minutes. I wasn't checking the site personally, just got an email from my tracker. Probably just an error or See tickets fiddling around for Friday ticket sales. Still, gave me a nice early morning heart attack!
Anyone else tracking https://glastonbury.seetickets.com/event/addregistrations get a change notification? Apparently it was at the " The booking site is operating at the maximum possible number of transactions." page. Back to being down now.
