Same boat as you.

TBB Speedtest

I was on bng1.th-lon earlier, dropped PPP, ended up on dsl6.th-lon, same speeds being seen.

Speedtest.net giving me full speeds.. what the hell is going on!

Things are pretty good on dsl1 for me tonight. http://www.thinkbroadband.com/speedtest/results.html...

BNG1 was looking good earlier this evening.

Alas, it then started to suffer from the single thread degradation one more!

I'm on DSL6

Still no improvement, even normal web browsing is getting slow and quite bad now. I'm on dsl1.th-lon now.

What's going on Zen, sort it out. No reply from Zen on this thread since Monday and my support ticket has had no reply either.

I joined Zen in 2006 from Plusnet, after Plusnet service and reliability went downhill. Don't let it happen here, your user base will start going down.

Support ticket id: [7879929:5637349]

I don't know if this is relevant? Still looks like pie in the sky!

Hi all,

Thanks for your patience on this. We're still working on the reported issues, but I would like to provide a quick update.

Following some BT maintenance on our connections to them in London, we noticed a potential issue with a part of the network that brings traffic from the BT nodes into our network. The emergency maintenance above was indeed to isolate this path, and we've seen an improvement following the work.

As some of you have also spotted, we've deployed some new hardware to provide extra capacity on our London broadband platform. This new generation routers give us a lot of extra capacity for future growth.

We're also continuing to investigate a related issue with Openreach, as in at least one case, we've narrowed the problem down to be outside of our network.

As you can see, there are a number of activities going on around this, but hopefully you should now start to see improvements. The updates from everyone are really useful, so please keep them coming.

As always, please let our tech support teams know if there are any issues. In the meantime, I hope you enjoy your long weekend!

Regards,

Jon

In reply to a post by summat:

I also notice that while I always end up on dsl6.th-lon, other gateways (I've seen dsl4, dsl5 before) are mentioned within the debug output of the PPP daemon on my router as it's establishing a connection, but I always end up on dsl6 in the end.

Just to add some explanation to this - yes you're right. As you have IPv6 enabled, if your connection comes in to a gateway not configured for IPv6, it will be forwarded to one that does, which in a lot of cases, will have been dsl6.th-lon.

The newer gateways (bngX) are configured for IPv6, as Bran mentioned. As such, if you connect to this, there is no need for your session to be forwarded on.

Hope this helps,

Jon

Thanks for the update. I appreciate the extra detail.

I have noticed that things are much better and more consistent now, with it not mattering too much what gateway I land on. Hopefully it'll stay that way

Have a good weekend.

This makes perfect sense, much appreciated, Jon!

Also much thanks for the update on the single thread stuff. Glad to know its being looked at seriously.

Could you answer why though, that while my general internet use was pretty crippled yesterday, tbb speedtester was registering <5mbit even for the multi-threaded test, and a few other speedtest sites the same.. speedtest.net maintained perfect performance throughout? File downloads were very slow too.

I could literally run a tbb test that comes back at 3mbit, then immediately after start a speedtest.net and get 74mbps.. reliably.

@knight01 was getting the same thing
