Very High Latency 300ms-400ms

Lately we've been noticing very high latency with our Comcast Business Service.  All our equpiment is functioning properly with low latency.  Even when directly plugged into the modem, we frequently get ping times of over 300ms.  Here are a few Traceroutes.  It seems like gi-127-0-0-11-sur05.area4.il.chicago.comcast.net [68.86.185.241] is the culprit.

Re: Very High Latency 300ms-400ms

Hi! Thank you so much for your patience and for spending your time today to reach out to Comcast for help with the internet service. I am sorry to learn that you’ve been noticing that latency and for the inconvenience that this has caused you. I never like experiencing internet service issues! Thank you for sending over those trace rout results. You have reached the right place for help! To get started, would you mind clicking on my handle Comcast_Gabe and sending over a private message with your first/last name, address, and account number or a phone number linked to the account so I can have a look at what’s going on?

Oh no! I am sorry to hear that! Would you mind trying to clear cache and cookies for me and trying to send it over again? That should do the trick!
