OVH Bare Metal: Repeated “IP Unreachable” Issues, Hardware Tests Show No Faults
Hi everyone,
I'm running into a persistent issue on an OVH bare metal server (Debian 11) and would really appreciate any insights or similar experiences:
Symptoms: The server randomly becomes unreachable over the network (no ping/SSH). Only a manual reboot via OVH panel restores connectivity.
Frequency: Has happened 3 times in the past 2 months;
Resource usage: Load, memory, disk usage are all normal before/after;
Diagnostics: OVH performed two hardware checks, including Rescue mode SMART and memory tests — no issues found (CPU, RAM, drives, power supply, etc.);
Logs: Nothing unusual in journalctl or dmesg, no kernel panics;
No user error involved;
Server is stable in Rescue mode;
OVH says no hardware fault is detected, and offers further deep tests or slot migration — but since each test finds "everything stable", the root cause is still unknown and the issue keeps recurring.
🔍 Has anyone experienced similar random “IP unreachable” situations with clean diagnostics? Could it be something like:
momentary power interruption?
bad motherboard/power rails?
unstable switch ports / MAC flapping?
Any ideas or tools to help narrow this down would be hugely appreciated. Thanks in advance!

location?

over the last ten years or so, similar happened to my servers about once or twice a year.
noteworthy that at least in my case almost always all servers in the account lost internet connection (only have france locations though) but maybe not at the exact same second or minute.
in the old SYS panel it usually helped to add or remove a virtual mac or similar action on any IP to trigger some reload on the router or whatever they do there. in the newer OVH panel usually a full reboot is required though.
yet I do believe this is nothing to do with the servers itself, but rather "unstable switch ports / MAC flapping" aka problem on the other end of the network cable.
Change it
