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

Request timeout for icmp_seq 0

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.
