Dear nusenu,

thank you for your work and reminding.

Apparently the same recommended setup and version produces a high failure rate in one relay while having no issue with another at the same AS.

Even within the same relay but different instances you can experience a failure rate that is double the one in the other instance.

Any idea why this is the case?

Kind regards

Paul
