be-501-arsc1.northdade.fl.pompano.comcast.net Riot Games disconnects every 10 seconds.

A clean, repeating latency spike every 10 seconds on an intermediate hop is classic for:

• A congested or overloaded router in Comcast’s network
• A flapping or load-balanced link
• Some kind of scheduled process / queue issue on that device

There are documented cases of Xfinity having exactly 10-second latency/packet spikes specifically to Riot/Valorant servers that turned out to be a routing or peering problem on Comcast’s backbone (one well-known example was tied to a node in the Independence, MO area). Riot support even confirmed it was on Comcast’s side in some of those reports.
