60% ping increase - possible things to check?

[anotherengineer]

So over the past several years cloudflare speedtest from my home to NYNY has been stable and repeatable at ~50ms ping and ~3ms jitter. The past few weeks it has been ~83ms ping and ~10ms jitter.

Don't recall changing anything. Ping tests to Chicago servers used to be 35-55ms now they are over 100ms?!

Thoughts? Using FF latest with ublock as only addon.
My son connecting things to network?

A 60% ping increase across multiple servers points to something on your side rather than the destination. A few things to check: (1) run a traceroute to your usual test servers and see where the latency jumps - if the first hop already shows high latency, the issue is local. (2) Check if something bandwidth-heavy got connected that is saturating your upload. Even small upload saturation can spike ping dramatically due to buffer bloat. (3) Check router CPU and memory from the admin panel - heavy AiProtection scanning, QoS, or too many NAT sessions can add latency. (4) Try a direct wired connection bypassing WiFi to rule out interference. (5) Check if your ISP changed your routing - sometimes ISPs re-route traffic through paths that add latency.

Did the high ping coincide with the start of Epic Fury? I hate to say it but traffic has increased, for whatever reason, maybe cyber attacks, since....

Yea ddos attacks probably and routing issues. It was not smart to start it but now everyone will pay for it even internet traffic xD

Ah hey, good point from jzchen - external traffic and DDoS routing shifts are real and hard to diagnose from inside the network. To definitively separate home network issues from upstream ISP routing: use MTR or WinMTR to your test servers and let it run for 5-10 minutes. Unlike a single traceroute snapshot, MTR gives you continuous hop-by-hop packet loss and latency averages. If your gateway hop is rock solid but latency appears and stays at a specific upstream hop, that is your ISP or their peering partner. Also worth a look at your ISP community forums - ISPs rarely announce rerouting but users often spot and document it there.
