Both OR Engineers did reset it at the exchange, although the first one said "it will stabilise in 48 hours and the speed at this point will be the speed it will stay at."
The 2nd OR Engineer said I will have to sit out the 10 days and my line will support 9.7meg. He also said that my speed during the 10 days shouldn't drop below 4meg, but it might re-sync.
I've not looked at the Stats this morning, but will post them shortly
