Hi, Codeforces! πŸ“± We'd like to share some exciting news: Telegram is back as our title sponsor! πŸŽ‰ This means we can keep developing and maintaining the system and, most importantly, running rounds for a long time to come. A quick throwback to Codeforces history - our relationship with Pavel Durov and Telegram goes all the way back to 2010, when Pavel first put his faith in our community and supported Codeforces development. Since then, our cooperation has continued, and Telegram has supported Codeforces in different ways over the years. We're super excited to have Telegram as the title sponsor again. This support helps us with every round we run and gives us a chance to do new things, too. Thanks to Telegram's new support, we've already started moving our infrastructure to a more professional data center, making the system faster and more stable. πŸš€ Expect more good news! ✨
