1. Logging on early appears to have zero effect on your place in the queue but definitely get in before 9
2. No sure way of knowing if extra tabs has any effect. People got through with a couple open and others got through but were locked out of the booking page. The risk is yours but I certainly wouldn't risk it if you only have one device.
3. Only refresh if you're on the booking page and you have problems or you get the 'all tickets have been allocated' message.
4. No solid evidence that the system favours one type of connection over another.
@Sziget2025_Leaks is there any chance for more alternative and punk bands like Idles, Viagra Boys and Amyl and the Sniffers like in the past few years?
