Lots of tweaks and minor adjustment to wording, and still some work today now Talk Talk have finally updated the file format, but so far so good.
We have had loads of people migrate to us using the new system without MACs.
Next week will be no migrations because of the change of lead time from 5 working days to 10 working days.
I wonder how other ISPs are coping.
P.S. Thanks to OFCOM and ispreview for kicking TalkTalk.
