Last Friday (the 20th of Feb) I realised that my ping had noticeably increased, from a mare 4ms all the way to 20ms. Upon further investigation I found that my sync rate on the download side had increased too, from 35.5Mbps to 39.2Mbps

So what I was wondering is whether or not this high ping and slight speed increase is a direct result of DLM? And how long it will last beyond the ~7 days that have past.

General stability has also taken a hit too, with pages and services regularly timing out and/or stuttering. I frequently game and use multiple streaming services so this
is a bit of a annoyance, although it's still a bit of a first world problem :)

I'm currently on a Spark Unlimited VDSL plan with a phone line too.
