For me 2014 was mostly ok, only occasional issues solved by a single ppp session hop.
Since dec 2014 the current issues started becoming apparent. In december initially it was a small drop of download throughput and nothing was affected, netflix etc.
Then in january it suddenly escalated and upload also started been affected, I also started to need multiple ppp session hops to recover performance. In addition during 2015 the peak time on tbb graphs started getting worse after a big improvement in q3/q4 2014.
On multiple occasions I have not noticed by doing speedtests but by services suffering e.g. iplayer stuttering and taking minutes to buffer 10 seconds of content, netflix stuck on SD, youtube taking ages to buffer etc. Everytime these issues occured I was always able to resolve by hopping the ppp session. Also speedtests were slow on tbb half the time upload speeds were also affected.
Then during march I managed to find a good endpoint (or good bTw routing if thats the issue) and performance was solid for a number of weeks, I even started to wonder if something had been fixed. Then last week I by mistake hopped my ppp session and BAM problem was back.
I thought I found the good routing/endpoint again after approx 10 hops one night bu tthe problem was back the next night, then after another 20-30 hops I found good performance again and I have sat there since.
In my case plusnet confirmed my SVLAN has blue status. I have also 'always' been able to recover performance by hopping even tho it now needs much more hops to do this as if the problem is getting worse.
I do think igniotion has a partially valid point when he says plusnet are within their rights to have network saturation, however where I think he is wrong is they should be open about it, if their equipment is the source of the problems then they should say so and make it clear the current performance is now the norm for plusnet. As jelv has pointed out multiple pages of the website say expected performance at peak is line speed, and it also should be made clear plusnet have stated multiple times an advantage of using their servise is their QoS system helps the user at the line level, but of course if the line cannot reach line speed then plusnet's QoS doesnt work as it relies on the line been able to reach line speed, not to mention that plusnet staff have stated multiple times in normal situations their network will not be the point of congestion.
Aside from marketing reasons I suspect a reason why they are not been open is the new ASA rules, a isp selling unlimited usage can only do moderate throttling, and deliberate congestion can be seen as a form of throttling. So it could be a plausible deniability game.
