Loads on there for me, Saturday: OCS, Royston Club, The K's, The Snuts, Amy Macdonald, Pixey, Overpass. Will also watch The Wombats and James.
Sunday: Stereophonics are the big one of the weekend for me, was either this or book a hotel etc for one of the other tour dates so glad it's worked out this way. Also Sigrid, Wunderhorse, Starsailor, Nieve Ella and Chloe Slater. Hopefully Inhaler, though they could be opposite Stereophonics
I don't think we will see Iron Maiden at Download again. They've realised they can book cheaper headliners and still sell tickets.
Ghost, Blink 182, Parkway Drive
Putting the queuing system to one side, when I got through the website was far more stable than previously. The payment went through without a hitch, it let me click back and forth to check different coach times without the webpage dying and kicking me off.
So from that front, once you are in, you are in and it should work.
Its all luck, but I had one tab open on Edge, Chrome and Mozilla (Edge winning the day). Each one had a different ID number. I was also on a work WiFi that goes through a VPN which I checked with the Akamai link prior too.
