I’m using Hetzner as well and the telia backbone is sh*t even if you try from germany to reach the server which is located in germany (not the ones from finland). This dosen’t only affect the UDP 123, it’s the hole traffic. Sometimes SSH connection drops / just pause, other people reports that download and webtreffic is horrible slow.
Hetzner will route your server via DTAG (Deutsche Telekom AG) for an extra fee of 5€ per server. That backbone works very well.
