Just thought I'd post an update.
Around late October/early November the daytime performance was about half my normal. But around mid-November it recovered and has been solidly normal ever since.
As mentioned earlier, given my 2-year deal was coming to an end I rang them at the beginning of January. They were happy to continue my discounted deal on an on-going monthly contract. That'll do me.
As an aside, some friends who are with Eclipse are moving home. Rang Eclipse who were only too happy to process a normal house move for them.
So for me it looks, for the moment at least, as if it's business as normal. But as now on a monthly deal I can more easily move if I really have to.
We have more and more laws, and less and less enforcement
