speed - AGAIN


[link to this post]
 
so after reporting I was getting around 400Mb download speeds on my 1,000Mb connection (uploads are fine), your support staff have been tinkering with my router settings apparently and have managed to get me down to sub 100Mb download speed tonight... well done.

My norm is around 850 down and 950 up.

EVERY TIME you do some planned maintenance, my connection gets shafted one way or another...

Whats worse is the circus you put me through EVERY time asking me to confirm my hardware and software settings - even my choice of browser (as if that affects download speed) and CPU load. What a joke. This is my 3rd loss of speed or total loss of connection in as many months. You folks really need to work on your own service provision.

Sunday morning 8am and download speed has gone back up to 738Mb which is just about acceptable.

I'm guessing now, since the speed drops off a cliff later in the evening, that this may be a contention issue?

could that be the problem?

My development has around 250 apartments. Not sure how many took up the connection with H/O but lets say half, given the broadband provision beforehand was appalling... so maybe 125 or so users all at once streaming movies, TV etc...

It definitely sounds like congestion/contention which would be more noticeable on the higher end 1 Gig service such as yours. Have you reported this to Hyperoptic? Will be interesting to see if they admit they have capacity issues or whether they they refuse to admit this point blank. Just be aware that in some cases (especially in London) they use Openreach leased fibre so perhaps they haven't purchased enough bandwidth from OR for fibre to your block.

Which city are you located in, out of interest?

Also, in their defense, I've noticed that Chrome does post slower speedtest results than Safari on my macbook pro, so asking for the choice of browser isn't such a bad thing.

back to sub-100Mb this evening.

Not quite as bad as Sunday when it dropped to less than 5Mb on a 1,000Mb connection for a time.

I'm in Edinburgh.

H-O have escalated to try and find out what is going on.

Historically, the only issues I've had with them have been traced back to me having a £5per month fixed IP. There's only a handful of us in our development that have a fixed IP and we are always the users who seem to suffer.

When I came in from work, the download speed was about 500Mb, now later in the evening its back to around 70Mb.

I don't know enough about routing, but from a traceroute I copied from you on a previous thread, it seems I am routing through new york again?

I'd be grateful if you could cast your expert eye on that and see if it looks crazy?

Why a traceroute to Netflix that may well be a US based service for some things.

What route does a trace route to say labs.thinkbroadband.com go?

Oh and my results for the trace to 37.77.186.142 are the same as yours from the gtt hops onward.

Of course, Hyperoptic are passing the traffic over to GTT on (in your case) hop 9. So after that it's somewhat out of their hands; it's then up to GTT to find a route for the traffic to that IP.
What i'm not sure about is how Netflix's system works out which cache of their videos is best to send a user to; it could be an issue there.

However, surely the highest bitrate videos from Netflix are "only" 30-40mbit, and for every concurrent device you use, that'll open a separate connection, so it shouldn't really matter?

In my part of London, they have been installing their own fibre rather than leasing ones from Openreach, which is what they initially did. I don't know if it's their policy to do this nationwide
