Water damage to node, tap, connectors, or ground block Nonstop lag spikes after storms even though technicians replaced everything

Hello I’ve been having issues for over a week now and it’s been very upsetting because I’ve basically been paying for internet I cant use. I've had three tech visits this week. Node, tap, and cables were checked and tested but I'm still getting lag spikes and packet loss in online games that started right after last week's bad storms. I ping tested my connection in the command prompt and it show consistent ping from 10 MS to 20 MS but every 1-2 minutes it would go up to 200+ MS and this is the same thing that happens in online games that makes me lag. I think this might be post-storm upstream ingress/ noise or water damage to node. Ive had these issues for wayyyy too long.

I think the ground block, nodes, connectors, or tap got water damage which is causing this latency lag because before the storms my internet worked perfectly fine but the technicians look at me crazy when I tell them that. The weird thing is my internet speed tests are perfectly fine it’s just when I play any online game theres lag spikes or latency issues. I also noticed on the technicians phone my latency kept spiking over 100 but he said it was “normal” which definitely didn't seem normal. Ive tried Rocket League, UFC 5, NBA 2k26, Call Of Duty, Fortnite all on Xbox and PC and they all have issues. I NEED ACTUAL HELP PLEASE IVE HAD 3 TECHNICIANS COME AND NOTHING HELPED. SOMEONE PLEASE HELP ITS BEEN 12 DAYS.
