Wigan area got the upgrade and not good news, friend of mine there had cable for years the 50mbit tier. His service was generally fine (has moderate jitter but otheriwse ok), then when they uplifted his speed suddenly his downstream speeds are low, upstream is about 70-80% of max, iplayer buffers, jitter shot up. We checked his upstream channel and it is docsis2 qam16 so didnt fall back to qpsk. Simply looks like a balls up with underestimating extra capacity needed. Doesnt bode well for my port which has a history of utilisation issues.
