Has anyone else been suffering broadband issues recently (Perry Vale ward)?

Ours has glitched out several times over the past couple of weeks. Calls to our provider - not Virgin! - have (sort of) rectified it, but it still seems up and down and not back to previous speeds yet, even at times you would expect the levels of traffic to be low. They told me that something had caused it to re-set at low speed for stability reasons. I've noticed Open Reach vans in the area so wondered if there's been some general work going on. Or is it just us?
