Houston Xfinity packet loss to Zscaler Dallas datacenter

Company I work for let us work from home with Zscaler.  We are getting super bad performance (1Mbps) connecting to Zscaler Dallas (165.225.34.253).   Is Xfinity having saturation / capacity issues with Level3?

Hello, @user_4d7260. We want your service working great and I know 1 Mbps would make things close to impossible. This is a great post that goes over some different things to look at with your connection, https://comca.st/3hOpcsO. Please let me know if that helps or if you need further assistance.

FWIW, your packets are already 2 hops beyond the peering point / interconnection / Comcast webspace, so something else is going on besides a peering capacity issue. AAMOF, considering the physcal distance inolved, that RTT is to be expected.
