- Ripple CTO sees selective peer latency spike, rules out central hub fault.
- Bandwidth hiccup suspected after three out of 343 connections dropped briefly.
- Wider latency gap hints at capacity strain in CPU, GPU, or network resources.
A sudden surge in peer round-trip latency has drawn attention from Ripple’s Chief Technology Officer, David Schwartz. The unusual 15-minute performance dip occurred at about 1:59 AM PDT and has prompted discussions about potential network bottlenecks.
Schwartz, who is tracking latency at the application level, noted that the increase did not impact all connections equally. That detail has made the cause more difficult to pinpoint.
Investigating Possible Network Issues
Schwartz explained that if the hub itself had been at fault, the slowdown would have been consistent across every connection. Instead, the spike appeared selective, with only three peer connections out of 343 dropping during the incident.
Traffic dipped slightly, which he attributed to those disconnections. No other immediate anomalies were visible in the monitoring data.
Industry peers suggested possible causes, ranging from network congestion to regional carrier disruptions. One validator noted that backups or automated tasks can saturate bandwidth during certain hours.
In this case, Schwartz confirmed that the affected time was recorded in Pacific Daylight Time, ruling out confusion with UTC logs. He believes a temporary hiccup in available bandwidth is the most probable explanation.

Gathering More Data for Patterns
With only one day of detailed instrumentation available, Schwartz cannot yet determine whether the event was a fluke, a daily occurrence, or a random anomaly. To address this, he plans to integrate additional tools like Alloy and Grafana to expand monitoring capabilities. Detecting a pattern could reveal whether the spike aligns with automated maintenance, routing changes, or other predictable activities.
Moreover, network operators sometimes reboot switches or reroute traffic during off-peak hours. Such actions might ripple across connected peers, producing latency spikes.
Broader Implications for System Performance
Beyond this specific incident, the discussion also touched on the system’s baseline performance. Andrew Sperazza, XRP holder, observed that the latency distribution between the 90th, 50th, and 10th percentiles appeared unusually wide. This gap could suggest the system operates close to capacity in certain areas whether CPU, GPU, or network resources making it more vulnerable to small disruptions.
