Purchasing a Config 2026 ticket after it sells out

Hi, I just got the budget approved to buy my ticket for Config 2026 (my boss was able to get his 2 days ago). I just tried to purchase one, but now it is sold out. I am wondering if more tickets will be released after people cancel, or what I can do to get a ticket, as my boss and I are supposed to travel together. Please let me know what possible ways there are to get a ticket as soon as possible. Thank you!
