Debian Server Management

Debian is chosen for stability, and it stays stable when someone keeps it that way. We apply security updates as they land, plan major release upgrades carefully, and keep your Debian servers lean, hardened and fully documented.

Problems we fix

What goes wrong on Debian, and how we fix it.

Upgrade stuck on old releaseA server left on an old Debian release that no longer gets updates. Upgraded step by step, or rebuilt and migrated.
Mixed repositoriesPackages pulled from testing, backports or third-party repos causing conflicts. Cleaned up and pinned properly.
Mail delivery problemsPostfix queues, SPF/DKIM/DMARC and blacklists sorted out.
Services failing after updatesConfig file prompts answered wrongly, units that won’t start. Diagnosed from the logs and fixed.
