I was able to work around the issue with my old Cisco VPN software by creating a copy of the connection and using TCP, instead of UDP as the transport method. See earlier posting in this topic.
Others on later versions of the Cisco VPN software (Anywhere I think it's called) don't appear to be able to do this, although this may depend on how your company have configured VPN. It may be worthwhile asking one of your company techies to determine if you can use TCP for your VPN connection, rather than UDP. It is the UDP type messages that are being affected by the BT network.
So far, a number of people have reported issues occurring since last Tuesday, but there has been NO confirmation from BT that anything has changed, or even that there is an issue and therefore no statement that the issue will be fixed. We are just waiting in the hope it will be resolved.
Thanks all for posting. I’ve moved some other threads onto this one to keep it all in the same place, sorry if it looks a bit messy. If you haven’t already done so please email over the following details and we’ll investigate this for you.

I've emailed you my details, i'm happy to provide any other required information if need be. Hopefully you guys can get to the bottom of this.
I think when the vpn thing is fixed our consoles will be too along with them.
My PS3, PS4, Xbox 360, Xbox One and PlayStation Vita are all affected with this.
