Debian 10 "Buster" repositories have been moved to archive.debian.org, after which the distribution will soon cease to be available through the main mirror network. The removal of Debian 10 packages from mirrors for architectures not covered by LTS support is planned for mid-April.
Debian 10 was released on July 7, 2019, and was officially supported until September 2022. As part of the LTS cycle, updates for Debian 10 will be provided for the i386, amd64, armhf, and arm64 architectures until June 30, 2024. After that, an extended 'Extended LTS' program will be applied to the distribution, involving the release of updates addressing vulnerabilities in a limited set of Debian 10 packages for the amd64 architecture. Extended LTS support for the Debian 10 branch will be provided in a separate repository until June 30, 2029.
