Well, the plan had been to shut it down end of this year

Lost-Chall has been operational since 2007, witnessing numerous changes over the years. I've dedicated the past 10 years to full-time software development and juggling various hobbies that don't involve a computer. The journey has been both enjoyable and challenging, but I've reached a decision to close down the site. However, I'm open to giving it away for free to anyone interested in hosting the site. It's important to note that I was quite young when I created the site, and it doesn't adhere to best practices. There's a considerable amount of redundancy, and it relies on a framework that has been deprecated for many years (Zend) while still running on PHP 5.4. Given these factors, a proper migration will require some time and effort. If you're interested in taking over, please don't hesitate to contact me at lostchall@gmail.com. In the event that no one steps up to run the site, I plan to shut it down at the end of 2024. At that time, I will email a zip file containing the source code, allowing you to access the answers to unsolved challenges. Wishing you all the best, Bregi
There is a (tentative) replacement up on

This is still in experimental stage though, and is not in-sync with the latest database.
