TLDR: There's some days where the Gods of IT are not with you. Just lost a whole day of work.

So this morning, we (me and my team) big performance issues with our web app. Lot's of requests time out, big latency, etc

Try to ssh to VPS, latency of 10 seconds between user input and output.

Usual checks: RAM ok, Proc ok, hard drive ok, reboot server (20 minutes), update/upgrade

We decide to call OVH. After 15 minutes call, we try to reboot in rescue mode. Reboot fails at 60% + everything freezes.

After an hour, OVH opens an incident ticket on +200 vps instances (including mine) everything is down during +1h

Finally everything is okay ! Even had time to migrate my new database schema.

Still, quick heavy on the mind but feels good to go home with everything working out correctly
