I have a hypothesis that you could increase your chances of getting tickets for sell-out events by attempting to access the website from multiple locations. Just to be clear i'm not trying to be that guy who buys ALL of the tickets for events and then sells them on at 10X the price, incidentally i'm talking specifically about one event, Glastonbury festival, for which I have tried many years to buy a ticket, and never been successful.
The problem is that you literally can't get on the site when the tickets get released.
So i guess there area few qualifying questions to work out if i need to even ask the main question.
Which brings me to the actual question:
This has very little to do with your connection. The server is simply drowning in requests. More requests from different locations won't help you. A faster connection might help you get into the queue before anyone else, but multiple connections won't help. If you really want tickets, figure out how to move through the website in an automated way such that you submit a request to move through the menus faster than any human could.
