> Pay attention to the custom mtu trick.

I wish Hetzner made this more clear up front. Maybe a big red banner on the vSwitch page. I can't count the number of hours I've spent troubleshooting network issues at Hetzner that came down to MTU.

As someone who is trialing Hetzner is there a link to info on this?

The vSwitch docs tell you to limit MTU to 1400 https://docs.hetzner.com/robot/dedicated-server/network/vswi.... If you fail to do this it'll default to 1500 I think and manifest in unpredictable ways. Like being able to fetch updates one moment, then being unable to connect to the update server a few minutes later.
