CodeChef is a not-for-profit educational initiative started by Directi more than a decade ago. We started with a dream of seeing an Indian team winning a gold medal at the ACM ICPC World Finals. In its quest for the same, CodeChef has built a self-driven community of the world's best programmers. Today more than 1.3 million competitive programmers from 180+ countries learn from CodeChef. CodeChef has been hosting monthly programming contests regularly for 10 years now. Its platform has assessed 92 million+ code submissions to date, and over 30000 organizations are being impacted by CodeCheffers worldwide. It also organizes SnackDown - one of the world's largest global programming competition whose last edition drew participation from 140+ countries. Since 2017, CodeChef has started providing India's only industry-ready certification in Data Structures and Algorithms, and 1800+ programmers have been certified under the same.

Migrate to a good host like Krystal.uk. The difference is night and day. Then, host the file with a CDN like https://bunny.net or https://keycdn.com. Source: about 4 years ago
Use any hosting on the sidebar, and a CDN like bunny or key. Otherwise you'd get banned from a web hosting plan, either from DMCA or auto file uploads. CDNs are designed for constant file uploads and usually warn you if anything illegal is uploaded, or forcefully deletes it. Source: about 4 years ago
