Reorder mirror probing in misc/build.func and misc/install.func to scan global (OTHERS) mirrors first and fall back to regional mirrors—pick up to 3 random reachable mirrors and try them. Rename related variables accordingly and keep the fallback logic intact. Update tools/pve/update-lxcs-cron.sh to define region-specific Debian mirror lists, detect container timezone to pick regional vs other mirrors, and implement a fallback loop that checks mirror connectivity, rewrites APT URIs to use a working mirror, and retries apt-get update before proceeding with dist-upgrade. These changes improve resilience against local CDN/local-regional outages by preferring globally reachable mirrors first and providing an automated mirror-switch fallback.
