Can't access Google Gmail using mail client over Comcast Network

Four days ago trying to retrieve mail from my Google gmail account via pop mail is extremely slow or not at all.   If I switch from Comcast to another providers network from the same local LAN access to Google gmail is very quick.  Ran some traceroutes which only get so far and then dies to either being blocked or no route.  See below.   Anyone else seeing the same issue.
