Terrible packet loss after area maintenance

On Wednesday December 4th there was network enhancements done in the central CT area. Ever since it's come back, I have been constantly losing packets in every single game I play. Internet speed is fine, but I'll just be playing and then everything will lag for a few seconds while the network catches up. Why is this happening? I have restarted my gateway multiple times, checked cables, and checked everything and I am still experiencing packet loss in intervals of 5-10 minutes for 3-5 seconds at a time.

This needs to be fixed as it makes doing things from even work to gaming unbearable.
