Return of the Dreaded Slow Single Thread Download Test


[link to this post]
 
Is anyone else suffering again from poor speed on the Single Threaded Download Test on the Thinkbroadband Speedtest?
Especially Scotland in the Perth area and surrounding villages.

Noticed this on Thursday and has been like it all Weekend

Generally a Normal Speed Test

One from Thurs 11th

Like that all weekend, any time of day

Latest Test 15th

Will give a couple of more days to see if it returns to normal, then if not will drop Zen an Email.

You are not alone. There is a similar thread going on IDNetters for two IDNet customers on a Zen backhaul option.

There is also a shed load of engineering work going on at the moment if you look at the Zen website.

I wont say too much as I will get accused of being against small ISPs, but I have seen an increase in complaints on multiple forums.

As the story goes, you pay more therefore your Customer Service will be second to none and the issues will be resolved super fast.

Interesting stuff.

If you take a look here, you'll see that from midnight Sunday (14th), speed tests have dropped, consistently, to around 90% of what they originally were (so now clocking in at 45 Mbps rather than 50 Mbps).

Something has gone south for sure. Pointing the finger at Zen for this one (on IDNet using Zen backhaul). Not really fussed to raise a support ticket just yet to have backhaul switched, but I find it's interesting watching issues like this. smile

Just to point out to people on this thread Stanley exchange is not Zen back haul most likely TTB or BTW.

For those of us who research things before passing comments.

Seeing the same on Cloudscape, they use Vodafone backhaul.

They also are in the middle of some network upgrades, hopefully next week they will be online.

Time will tell....

Athough latest speedtest seems better?

Have taken a look at the peak vs off peak and single versus multiple thread results overall for Zen

And while when I search by hand all the results I can find people with the issue, the overall statistics suggest that things are not falling apart.

Put another way, in the evenings the single thread median figure is actually 1 Mbps higher than the daytime one, but this does flip flop from month to month as the sample sizes at Zen are too small for this to figure in the main news.

On BT backhaul with Zen.. Since Sunday download speed has dropped by 5 to 10% at all times.
BUT my single thread speed has NEVER been above 27.5mbs on a 80/20 connection. The multi thread connection is always good and steady at all times giving me just over 75mbs until last Sunday that is. Upload is over 18mbs at all times.
Regarding the single thread download issue Zen have told me that there is nothing they can do about that and gave me the impression that they couldn't make a complaint to BTW about it and making me feel that I should be lucky to have what I have and forget about single thread as it is not used these days!

I'm really surprised that Zen don't want to look into this for you. However single thread speeds don't form part of the contract with BTW / OR and therefore single thread speed issues don't constitute a broadband fault with an SLA for it to be addressed.

Thanks all for the replies.

I am on Zen GEA FTTC. In my Zen portal, I had a Zen Fibre GEA Migration Fulfilled on 08/03/2017 and my current line technology is GEA FTTC. The nearest Zen PoP to me I think will be Edinburgh.

Still the same tonight so will drop Ajays a PM and see what comes of it.

When I was with Zen last time I had this issue, they did something that fixed it and it was fine thereafter.

I've just moved back to Zen, having a slight issue, but not terrible. Might give them a shout and see if they can do the same again.

What's the issue? Your single thread speed only being within 5Mbps of the multithread speed?

Some of us use that as measure of success.

I have had the issue before myself,.
When it first reared it head earlier last year, contacted support and it was resolved. Had other odd speedtests with low single thread speed but it would only last a couple of days and it would return to normal, so never reported it.

Just signed up to the Big Deal Fibre in October, so are in contract till October 2019. Not that I am thinking about leaving as I think Zen will sort it again.

Sent a PM to Ajays so will see what comes of it.

Yeah I had it with Zen when I was with them a year or so back, but they fixed it fairly quickly, Once I'd PM'ed jongreen84 on here.

I forget what they did exactly, moved me to another VLAN or something maybe...

Then I left them, and now I'm back, and i'm back to the old problem....

I'm going to PM the ZEN guys in this thread. and get this sorted again.

Logged the issue with Zen support on the 18th, got a reply the following day.

"Thank you for contacting Zen Technical Support. We have identified an issue with the platform that your broadband connection is on within the exchange. There is an upgrade scheduled for this platform however this will take a considerable number of months before work is carried out therefore I have placed a request to migrate your broadband services onto another platform in the exchange.

This order will take up to 10 working days to fulfilled and you may have downtime of up to 10 minutes on the day the migration takes places."

See you in 10 days then.

Sounds like they are moving you from Zen backhaul to BTW.

Be interesting to see whether it improves things.

Quick update on Single Thread Download speeds.

Just about back to normal.
Within about 10Mbps of normal Single Thread Speed, just seems to fall away towards the end of the test and latency is back to normal, was up in the high 40s for most of the last couple of weeks.

Will just have to keep an eye.

I have had the same problem with single thread download speeds in single figures. Zen have moved me over to different equipment in the exchange and speed has improved to 60mbps the same as multi thread download.

Exactly the same issue, single thread rates have dropped to ~12 Mbps but on top of that I experience regular cuts, even during off-peak, daytime. I have contacted them and acknowledged the issue. Like the others, I will be transferred to another network in 10 days. That is quite a long time to wait considering the premium price of Zen.

I suspect the waiting time is due to Openreach. Switching a connection's backhaul probably has some kind of lead time like 10 days.

What a joke my latest speed is even slower than when I was on ADSL2+ £ 35-40 a month for a totally [censored] connection every evening !!!!

Download speedachieved during the test was - 15.27 Mbps
For your connection, the acceptable range of speedsis 40 Mbps-74.1 Mbps .
Additional Information:
IP Profile for your line is - 74.1 Mbps 25/02/18 time 20-20

Got a definitive date of migration last week: 12 of March. More than 10 business days to be honest. What is going on with Zen? Every time I had an ISP in this country it has been the same story: at the beginning very good and tech savvy, then going down the drain. At least Zen still has a good CS (they understand issues and call you back on the phone to update you) and they are still indeed tech oriented. But this is concerning.

I expect it goes through a similar, if not the same, procedure as a migration, where the end user has ten working days to change their mind, (required by Ofcom), and inform the gaining ISP not to let the move go ahead.

This sort of change is in effect a migration between wholesalers, ordered by the ISP.

Ofcom regard working days as Monday - Friday. Lucky them!

As discussed above I have been switched to a new backhaul, and indeed bandwidth have returned to good levels, even higher than they were before. I have to say the technical help was very good, they returned to me by phone. There was a hiccup (the internet was down for a few hours in the morning) but after I called it was swiftly solved.
