Random Internet Outages/Lag

Hello-

We've recently been experiencing a large amount of random lag/outages in our neighborhood. My Brother and Father live 2 streets over and they are also experiencing these random glitches. The modem always stays connected, but nothing loads during these times. I currently only have internet, but my brother & father are experiencing pixelated/grainy pictures on their TVs when this happens as well. We were notified on Monday, July 13th that teams were working and we were down for a few hours. Ever since then, we are getting random moments where nothing loads - this can last anywhere from 30 seconds to 2 minutes. 

I've power cycled my modem and I can confirm that when this happens, this impacts both computers as well as cell phones/iPads.

I'd be happy to share my location with a representative, but I'd prefer not to put it out in the public.

Is there someone that can look into the connections in our neighborhood?
