Could a Network Engineer look into this please?

We've been experiencing extremely high latency for the last one week to ten days. Yesterday was the worst.

I went to the local Xfinity store and they opened a ticket in their system. An hour later I received a recorded message that the issue I had reported had been fixed. I rechecked the latency and things had gone back to almost normal but not 100%.

Now this morning we're finding the issue back at square one. 

Below is the current latency status. It speaks for itself. The switch at line #3 was apparently rebooted yesterday but is back in trouble again. Looks that the switch has gone bad and needs to be replaced. If this is a cluster switch it probably is affecting a big swath of connected devices.

I'm submitting a redacted output. Location is Aurora, CO. Please contact me if you need the entire output.

Thanks

Ahmed

@Xfinity Support 

Hopefully, you'll get to attend to this matter soon. Meanwhile, I'll keep posting the information that'll help you with the troubleshooting.

The hop timings have dropped a bit from the 2000+ ms but are still bouncing substantially. Below are three readings from different times of the day today:
