Yeah I had a connection bounce sometime last night after midnight and lost my nice connection. One bounce later and it's back. Eight months on the problem is definitely still there.

I think I'm nearly at the end of the my contract so might as well look around for an alternative. Trouble is I'd rather not get tied into a long term contract when at least I know how to fix the PN issue when it strikes.

yeah, for that reason pulse8 might be worth a shot as there is no tie in.

Pulse8 FTTC is MPF. Full LLU. But still no tie-in, as you say.

Graphs and figures are now on the blog, not that it helps. Had to drop EE as not enough data from single thread testing, i.e. as with lots of people the faster to run web based test rather than the full flash test is preferred.

Perhaps it is one for a Plusnet Rep to answer. Their chance to sell themselves on their great evening service (or own up as to why speed tests do well in the evening).

Have you got any non port-80 analysis?

thanks for the analysis, I am baffled but it is what it is.

As that was analysis up to and including June 2015 the tbbx1 test was over tcp port 8095

i.e. this was before the single thread http tester appeared

Hi

This issue of single threaded and multi-threading testing is something I've seen just recently. My connection during peak time over the last week (around 8 to 10pm) drops from the usual ~74Mbps down to ~10Mbps on the single thread test, but usually manages to maintain > 50Mbps on the multi-thread test (10 * 6 = 60Mbps)

As I understand it, for the multi-thread test it is like me plus another 5 people, we each get around 10Mbps for this test out of the congested share so get a speed test result around 6 times better. Of course this means everyone else gets a little less bandwidth to service what looks like another 5 connections, but an extra 5 people for the duration of the test out of thousands sees a negligible reduction overall, so it works to give a higher aggregated speed.

When I'm browsing and downloading files however, I'm a single user, so see the reduced speed.

Annoyingly the BT Wholesale speed checker for reporting speed issues only performs a multi thread download, so gives the higher reading, and comes back that the line is performing within good parameters, although I don't consider downloading at 10Mbps good for 80/20 line.

Would it be possible to chart the difference between the two tests taken at the same time for each ISP. If congestion is a problem, this should see an increasing difference between the two tests during peak times, if charted with y axis as the difference and x axis as time, would should a trend upwards during peak times.

Browsing is not strictly a single thread, browsers will fire off multiple threads downloading the various components for a web page.

The numbers are in the blog for what you propose so someone can do the maths if they want.

I really think the issue for identifying the issues with plusnet is it is not affecting everyone, where for example congestion is pretty obvious on Virgin Media either because it affects more people or the impact on people across the board is a lot higher.

Tempted to try and add the AAISP, Zen, IDNet and other smaller WBC providers together in a 'super ISP' and see if the pattern repeats. If so its something in the BT Wholesale network most likely.

Another option is splitting down into the regions, but every time you split the data you make it more prone to noise.
