I've been having erratic issues with ping for a few weeks now. Thought it might be a recurrence of an earlier issue with my coax cable, but no longer sure this is the case. Router stats:

Today's BQM:

Sunday's BQM, with a random late-morning spike:

Nothing wrong with your Hub stats. Best to post a live link to the BQM.

Your latency problem is due to very high contention on your local part of the VM network.  There are too many users connected. 

There is nothing you can do except demand that VM provides more capacity. 

[Rogueywon]

I considered that, but a weird spike for a couple of hours on a Sunday morning seems an odd fit...

I shouldn't worry about that. A sudden step usually means that some network maintenance is going on. It does happen, even on a Sunday sometimes.

Hi @Rogueywon 👋,

Welcome back to our Community Forums and thanks for your post. 

I am sorry you've been having some issues with the service.

Checking on things this side, at the time of writing, I am unable to identify any issues. 

How have things been since posting?
