Registrar data, not DC overlap. Look at the LLC filing dates and registered agent addresses in Wyoming. I didn't say same network, same pattern.

SSH still works but root password changed. I can see my files in /home but cannot sudo. rsync running as my user, grabbing what I can. Database is the problem, need mysqldump and no rights.

If you have SSH, check for old cron dumps in /var/backups or wherever your panel stuffed them. Also try

find /home -name "*.sql" -mtime -7
. Most auto-installers leave artifacts.

This is why I keep a hot standby on Hetzner for anything that matters. 3 euro backup VPS, rsync every 6 hours, database replication over wireguard. Client never knows.

Hetzner is excellent value, though their DDoS protection is reactive rather than always-on. For gaming workloads we have seen packet loss during mitigation startup.

Wireguard adds CPU overhead. Benchmarked 12% hit on single-core throughput at 1Gbps. Better to use native TLS if your MariaDB version supports it.

fio, iperf, geekbench. results or gtfo.

12% of what baseline though? My Wireguard on a 4 core ARM box does 800Mbps no sweat. Context matters more than numbers.

my cloud. my rules. my 3AM alerts.

In Rust the context is the type system. The compiler proves your tunnel is sound. You cannot ship a Wireguard config with a race condition. This is why I run my entire mesh in rust-wg.

Nobody asked. Jonas needs his database, not a rewrite.

Found a 3-day-old .sql in /home/jonas/softaculous. It's 80% of what I need. Missing yesterday's orders but client will live. rsync still running, 40 minutes left.
