I'm experiencing periodic latency spikes with my Sonic Fiber internet connection. Using packetstats, I've noticed spikes ranging from 150 to 250 ms over a span of 60 seconds. I've tried various troubleshooting steps, such as power cycling my equipment, using different devices, and directly connecting my device via ethernet to bypass the router. I've also checked with my neighbor, who has the same service, and they are experiencing similar spikes. Is this kind of performance typical for Sonic Fiber? Also, how reliable is packetstats for diagnosing this issue? I'm hesitant to pay for a technician visit, especially given the high costs associated with it after being a long-time customer.

Latency spikes can occur for several reasons, often related to bandwidth saturation. This might be due to your own activity or someone else using the same network path heavily. Running a traceroute to a site like Google can help you identify where the lag is happening. My bet is that the service provider may have oversold their available bandwidth, leading to these issues for you and your neighbor.
You should definitely share your traceroute results. It looks like there's a significant delay at hop #6 where the ping times jump into the thousands. This could indicate a problem at that specific node or elsewhere along the route. If that node belongs to your ISP, they're likely to be the ones responsible for fixing it.
