Intermittent Network drops post road work / upgrades

Since xfinity road work that occurred last week for an undefined 'upgrade' our network connection has been dropping very frequently and consistently.  To rule out any 'home network' issues, I have hard wired direct to the Xfinity X8 Gateway / Modem device for testing and troubleshooting.  A line tech came and tested the line which tested fine and replaced the X8 Modem. Download speeds are typically 800mbps +. Upload speeds have a ceiling of 40mbps for an unknown and unresolved reason.  I wrote a simple utility that every 2 seconds simultaneously pings the Xfinity Gateway that I am directly connected to, the first hop in egress traffic to Xfinity and a google public DNS server.

Below is the output of the failed runs from a ~ 4 hour period.  Every single time we see our streaming connection drop or hang or picture quality degrade on TV's, Mobile devices, etc. we can directly correlate to when these pings drop. The DOCSIS / CM event logs on my gateway certainly would have T3/T4 timeouts in them but those logs are not exposed to me in the gateway mgmt.

Has anyone encountered this and worked it to resolution with Xfinity?  The line tech that showed up today was great and thorough however this issue is unlikely to reveal itself on short line test.
