I'm on plusnet ads2+, connections been stable for years with great sync speed.
Around 8am this morning, a bt openreach engineer pulls up next to the telephone pole which I'm connected to. He was up the top of the pole and in and out of a house down the street for around 3-4 hours this morning. I didn't really think to much about it until this evening when I noticed my internet felt slower then usual. When I checked my router, it said I'm having line drops in the logs and now I have a lower sync speed to the exchange then normal.
I hope its going to sort itself out soon, rather annoyed I've lost a few Mb in sync speed because of them today.
