2000+ Latency every 10-11 mintues after storms knocked out power

We had storms that knocked out the power for a few hours a few months ago. Once the power came back on, I went back to gaming and noticed that every 10-11 minutes, we would have a considerable latency spike of 2000+ms lasting for 5-10 seconds. Then, the latency would return to normal, and the 2000+ms latency spikes would reoccur every 10-11 minutes. It has been a few months since this first happened, and it has become incredibly annoying, primarily when gaming. I have done everything I can to reset/restart all my devices and routers, changed the cables, etc... I ran PingPlotter, which now is clearly showing that the issue is with this ISP address (Specifically the server named be-501-arsc1.pompanobeach.fl.pompano.comcast.net). It is showing 90%+ packet loss almost consistently, even during or not during the latency spikes, and I am now trying to figure out what to do and how I could get this fixed. I have tested this with all my devices, whether wired or not.
