  • Description
    We're currently seeing issues with the vSwitch. This can cause packet loss, higher latency or dropped connections between servers on a vSwitch. Our technicians are already working on it.
  • Resolved
    There are no further reports of this issue at the moment. We consider it resolved for now. The cause was a problem with the MAC learning of the vSwitch. Please also consider reading https://status.hetzner.com/incident/52a3c458-f6dd-41a4-b617-dd6d059c512f

  • Watching
    Right now the vSwitch should work again. Please flush the ARP table on bare metal servers. Let us know if there are still blockers and include a description.
