After my complaint to
www.ispa.org.uk I got a call from VM and was told that I would get a call from a senior tech yesterday. I did get the call and it was from the Chief Execs office, a very nice man listened to the issue and agreed it was a problem at VM, he was technical and understood the issue fully. We did a few more tests and he then got another tech to call me so that I could provide some additional trace logs which would help them.
I have since had another call from VM today who said that they had identified the issue and that is should be resolved and would I mind testing my internet without the proxy.
Great news it appears that the issue has indeed been fixed, it was some sort of routing issue which started on the 11th Dec. Hopefully this has now been fully resolved and we should all be fixed. Let me know!
