Use different ISPs. A lot of my friends make it a mission to buy Glastonbury tickets every year and there is one person who is always easily successful while everyone else struggles. His secret is to do it at work which is a large business news channel, they have a large preferential connection to the internet that seems to have the ability to power through internet queues.
Use your home internet connection and a mobile internet connection on another device if you can, might increase your chances.
