And is if by magic it is now working

Yep, the magic fairies have been along and fixed it.

Working now (ChromeOS)

Regarding the speed test results, I've also noticed the ThinkBroadband test seems to show much lower single thread speeds on Virgin Media compared to other single threads tests. This has been going on for a couple of months, previously it was very accurate.

Here is an example taken within the last few minutes:

TBB: https://www.thinkbroadband.com/speedtest/14955700808...
55Mb / Burst 69Mb

DSLreports set to a single thread:
http://www.dslreports.com/speedtest/15718143
154 Mb

testmy.net
153 Mb
http://testmy.net/db/u0YMvDjX1

Test file downloads from ThinkBroadband always reach the speeds reported by dslreports and testmy.net, it's just the ThinkBroadband test which seems to report much lower single thread download speeds.

Once multiple thread tests start to show that congestion on traffic over the LINX route is resolved then will investigate.

Might have some play versions for you tomorrow

The explanation seems rather biased against certain network technologies:

"Bufferbloat is a measure of how delayed packets are due to excessive buffering in broadband routers and other locations on the Internet.

A is good, F is bad and is only something to be worried about if you upload a lot while also downloading or vice versa."

I'm reliably informed by my son that our connection is actually very good in terms of latency/lag when playing LoL regardless of what others are doing in the household.

VM can fix this, at least for those using the hubs in router mode, if they choose pretty easily. Fixable via configuration on CMTS too as long as the firmware support is there. See below from MSO Comcast in 2013.

It's biased against certain implementations and configurations. DOCSIS 3.1 contains fixes by default.
