Intermittent Drops and Frayed Cable

Hello!

Within the past few days, we have been experiencing intermittent drops in the cable internet connection. The Wi-Fi and wired connections are working correctly; it's just the connection that drops for a minute or two. Otherwise, the connection has been working well, with 982 Mbps down and 24 Mbps up.

I went outside to inspect the coax that comes into the house.  A section of coax from the utility box is exposed before going underground to the house. The yard guy's weedeater may have hit it as there are several frays with exposed shielding (photos attached). I'm not sure if this could be the cause.  The coax that comes up at the house looks fine.  It goes to a grounding block and then a straight run to the cable modem (with one or two couplers).  For the cable section from the utility box to the grounding block, is that Xfinity's responsibility for possible repair/replacement?

I've logged into the dashboard for our Arris S33, and it looks like the SNR and Power are mostly within spec. However, there seem to be a lot of Uncorrectables on multiple downstream channels. The Event Log has only a few T3 and T4 timeouts but quite a few MDD message timeouts. I'm not exactly sure what all of that means.  I can provide the data in a separate message.

Thank you!
