The burst starts ok, but then it appears that something is throttling back speeds. Its highly amusing watching a TBB speed test and the dial flick all over the place.
So far Ive been on central10.ptw-bng01 & central14.pcl-bng02 and they are both as bad as each other
Plusnet appear to either be suffering from congestion or experimenting with something.
I still havent got a response to why speeds over the past week have been limited to 12-15Mbps on single thread.
The only input from Matthew stating the following sounds rather ominous.
Quote whilst I can't tell you exactly what we're doing I can confirm we're working hard on resolving it
Can we please have an update on wth is going on please.

Hopping will change endpoint's and even can change the routing thru BT wholesale, a lot of isp's if you congested you screwed.

Quote from: Matthew Just a reminder that the problem we’re investigating doesn’t seem to increase latency or packet loss, it only limits throughput, and only on a single TCP thread. If anyone is seeing packet loss or latency, then this is a separate issue and we'd urge you to raise a fault.
Does that imply it must be a problem with Plusnet's traffic management / classification system? Perhaps it doesn't have enough CPU power to handle all the bandwidth.

My bolding
Quote from: Anotherone
Quote from: fibreuser I have been running some tests for PN and there is something odd when downloading files single threaded. They appear to start at line speed and then all tail off just like the graph, does make me wonder if its a traffic prioritisation problem
IIRC, the idea that some of these problems may be related to an issue with Traffic Management, came up some considerable time back with some previous problems.
Has anyone from Plusnet / or is anyone, looking at this aspect at all?
And
Quote from: Anotherone That doesn't mean that I'm not questioning whether PN's Traffic Management has a hand in these issues.
And considering the various removals of network data in the recent past, as well as the lack of response to this aspect, I think that tells us a lot.

Sorry for the delayed update. We are still investigating at this moment in time and whilst I can't tell you exactly what we're doing I can confirm we're working hard on resolving it.
Just a reminder that the problem we’re investigating doesn’t seem to increase latency or packet loss, it only limits throughput, and only on a single TCP thread. If anyone is seeing packet loss or latency, then this is a separate issue and we'd urge you to raise a fault.
That update. OK, not very detailed, but an update none the less and shows they are still working on it.

Quote What update is that?
Exactly, we've had nothing now for nearly a week. During that time Ive had some abysmal speeds and to the point where my connection was useless for http.
I moaned last night because things were bad again, and I had to go gateway hopping... yet tonight Im on pcl-bng2. Latency isnt quite as good and although speeds aren't perfect, they are within acceptable realms.
I'm out of here soon but just wanted to report that tonight things are okish, but something is still very wrong in the fact that we should have to go gateway hopping to get a half decent connection.
Im disappointed at the lack of information coming out of Plusnet, whats even sadder is the amount of users Im now beginning to see giving up and simply migrating away because of issues over the past few months.
I can't believe that Plusnet dont see what is happening.
I actually raised a ticket because I was unhappy at the throughput. It took 5 days for someone to respond who hadn't even read my ticket properly and all Ive had so far is the generic 'test from wired' & 'do a BTw speedtest' which if they'd read my ticket properly they will see all this information was given a week ago.

edit amend wifi to wired

Nothing out of the ordinary visible on TBB BQM or speed test, however.
Something I've experienced before with PlusNet...
Could be the BRAS, I suppose.
Impossible to pin down, basically, so not going to try!
This is just for the record.
Troubleshooting: The Limitations of Traceroute & Ping
Latency: Connection "fast" but internet sluggish? Bufferbloat FAQ
Black Holes: Worth noting that the Plusnet Hub One router has an MTU of 1488 bytes.

Who remembers the days when 10mbps cable was like the best thing, and having it you noticed the difference... web pages used to load soooo fast, gaming was awesome...
Then we had to go faster and faster and now we have broken internet.... yeah sure I can download a film in seconds (700mb @100mbps) but everything else is shocking

e.g. blocking javascript and any 3rd party domains on a website causes them to be lightning fast.
Unless of course the isp is having issues 😛
