Here's what I'm getting just now... (sorry, can't get embedded images to work on this forum for some reason)
You might consider setting up a broadband quality monitor using http://www.thinkbroadband.com/ping
You have to register.
My one clearly shows when BT were working today (thick red line of packet loss after 11am). It also shows increases in latency at peak times and around 5% packet loss:-
I've got back to my ISP but I'm not hopeful as this has been going on for a couple of months.
Where are you located Macal100?
According to my ISP Openreach are looking at this although the latest report from them was that they'd sorted it.
I haven't seen any improvement.
Nothing showing up on their service status pages.
I was down at 0.5Mbps with 10% packet loss.
Have you raised a fault with BT? I suspect the people who need to know you are having problems won't know unless you do this.
Incedentally I don't think 30Mbps would be acceptable for an 80/20 package at peak times!
