Why does the mean path delay vary so much from one sample to the next?
Why does the mean path delay vary so much from one sample to the next? Does this suggest network congestion or path asymmetry?

The Precision Time service is provided over Equinix Fabric, which is a "non-PTP aware" network. Jitter conditions can keep changing on the Fabric. Therefore, you might see a mean path delay that varies a lot, compared to when you connect through a non-Fabric network.
