Just got home and first two speed test (BTW tester) gave 156Mbps down, then 175Mbps down. Both upload speeds were over 25Mbps and pings under 25ms.
Still nowhere near the 250Mbps I usually get, but how long will it be before it falls over again? I hope BT have been able to identify the cause of my (and several others') problems and have a plan in place to fix it.
My infinity in Walnut Tree went down completely on friday afternoon, engineer came out and fixed it today. Turns out it was damaged fibre a couple of connection points down from me. Wonder whether that was causing the latest problems. It's fixed now.
I think Andy knows his apples from his oranges...
Speeds now are back to normal - last test just now was 241 down and 27 up. 240-odd seems about average for peak evening times for me.
