Can't connect to Webex and any of their sites

 

I migrated over to 1Gb from 300Mb a week ago, and all was looking rosy until today.  Since midnight today I've not been able to connect to Webex or any of their servers or sites.  This is a massive issue for me as Webex tools are essential for my work.  All other sites I use seem fine, just webex.

If I connect a VPN (1.1.1.1 or my work VPN) I can connect no problem, but just using VM without the VPN it seems there is a routing issue.  

An example of ping and traceroute when it doesn't work here:

 

MacBookPro-13in ~ % ping mycwt.webex.com

It does feel a little bit like this thread which didn't get solved.  Any core network folks from Virgin want to comment on it? Routing issues leaving Level 3 networks in the US?

Thanks loads.
