Ahhh I had assumed probably wrongly that he came from be too. Well it would be about time Sky gave better speeds it would make a fair few people happier.

I'm am indeed ex-O2, but I moved to Sky 3.5 years ago

Certainly feels like the Sky DLM system has been reprogrammed to be much more "generous" with speeds than it has in the past. Judging by my noise margin variations there's nothing to suggest my line is considerably less noisy that it has been over the last 3.5 years, and I have manually requested line testing to be re-started on a few occasions just to see whether the end profile increases, and it never has. Add to that the fact that upstream is hitting 1.3 meg these days as opposed to the previous global maximum of 1.15 meg is a strong indication Sky have altered the DLM system somehow.

My gut feeling is that Sky are updating things exchange by exchange and then kicking off DLM so that the new improved profiles can be applied. Unfortunately it will be hard to determine whether people's speeds on ADSL2+ are indeed increasing globally on Sky, since people only tend to say anything when their speeds decrease.

Whilst this is largely a good thing, the initial reasoning for a strict DLM was to ensure stability was foremost important. To be honest with so many people having poor internal wiring setups I believe the idea of stability over speed was a good approach.

If suspicions are right and all of a sudden Sky DLM becomes much more generous we may see more complaints. Why? Well a lot of people do not use the master socket, have some cheap Argos DIY extension lead (usually flat cable) or may have star wiring. A strict DLM meant that these users got slower speeds with Sky than they would with say O2 but this also meant that Skys line did not drop out, whereas O2 with a faster speed probably would have dropped out more often.

Now if Sky DLM becomes generous and suddenly drops all of these peoples noise margins and gives them better speeds they will suddenly start complaining about disconnections. They will take the attitude of 'it was fine before and it's not now' and immediately blame the ISP when actually their setup has been awful all along. Try telling the customer that though, chances are they will just switch providers and the issues will no doubt follow them or they will get banded at a very low speed by another ISP and assume again, in ignorance that their setup is fine... The saga continues

Of course it depends how much more generous the new line profiles are. Although it might make it more likely that people will be given 3 dB, I strongly suspect the system will still give 6 dB to lines that can't handle 3 dB.

However 3 dB on a noisy line still isn't a disaster. Let's say a customer's line is noisy and only supports 10 meg @ 3 dB (on a bad day).

On a good day, customer has 12 meg @ 3 dB and the line gets noisy and drops. When the line re-synchs the noise will be taken into account and the line will come back up at 10 meg @ 3 dB. The line will then stay up because the noise on the line has been taken into account during the re-synch.

I also suspect that if noise on the line started to drop the line frequently, line testing would re-start and quite possibly assign a 6 dB profile due to the noise.

From My Sky:

Line connection testing completed on 16/06/2014, resulting in the following settings:

Download speed setting
Your connection has been set to a download speed of up to 22.0Mbps .

Upload speed setting
Your connection has been set to an upload speed of up to 2.6Mbps .

The upstream cap is interesting, I haven't got Annex M enabled on my line, but the upload speed setting is certainly suggestive of it.

Interesting

wasnt sure they were going to offer it.

Well I contacted Sky via live chat and it seems it must work on both kits. I am now on the 3db profile but the Easynet kit I think still adds 1.5db to the upload by default as that is on 4.5db. Anyway good improvement, almost on the old speeds I had when I was on Be There.

I am connected to the Easynet kit too, and I am now on the same profile as you. My upstream has improved to a bit over 1.0mb/s, but it's still not close to the 1.3mb/s I had from BE. Could you confirm what upstream sync speed you're getting now and whether it's fastpath or interleaved, and what modem you're using?

Thanks.

Over a month ago, I spoke to an ex-Be guy on the Pro team and asked to be put on fastpath; my synch speed went up from 19.5 to 21.5Mbps downstream. The upstream went up only slightly from 0.95 to 1.1Mbps. Also, the latency improved dramatically e.g. ping to bbc.co.uk used to be around 17ms and now it is 5ms. However, the various speedtests at different times still do not reflect the above-mentioned speeds.

MySky reports 24Mbps and 1.3Mbps on my profile. I am using a Draytek Vigor 2820n with the latest firmware. Also, I was told at the time that DLM cannot be running concurrently with the fastpath profile. Ocassionally, the noise margin also drops from 3db to 2db, which is probably too low and might be the cause of dropouts. However, I can live with the fact that the service is finally usable - even though it is not the same as Be.

I have to agree with this finding.
I initially synched at just under 20Mb and now with a 3dB snr at just over 22Mb but haven't seen any real world increase in speed testing results.

Just looked at mine. I'm pretty sure I was on 6. I'm now on 2.8.

Uptime says 371 hours.

It's a pity I can't release the upstream. That's still stuck at 8.8 &1172kbps.

go on reboot the router and see what you can get. You know you want to. I never reboot my router, I just wait for the power cuts every 3 months to do all reboots
