Mine has seen a lot of red and amber recently. Currently its amber.
My current ISP is ADSL24 -
In that case the Max Premium should give a bit of help, but beyond my ken to quantify it. The Max Premium prioritises within BT systems, which is where you are until you get to the handover point to ADSL24. Or at least to the underlying wholesaler - Murphx?
There can also be congestion at that handover if the underlying provider doesn't rent enough capacity off BT Wholesale.
What's the expected fix date? What exchange is it anyway?
The increase you would probably get in upload sync and speed is of course a consideration, but not the main one.
