What's happened here then? ECI cabinet. Apart from crosstalk dropping me down over the years I've never had interleaving on:

Virtually exactly the same before and after stats as me and interleaved was applied last night also for me.  Also an ECI cab sufferer.  Ginp can't come quick enough IMO.

My DslStats showed a mega amount of ES hit 1000/hr at one point, the auto mass effect detection should stop interleave being applied but this has never worked and the ECI cabs are as twitchy as they can be and apply interleave at the first opportunity.  I stand by opinion something has changed in this regard in the past few months.

I put it down to the weather and thunderstorms even though there wasn't one near me.  If past experience is anything in 10 days or so hopefully it will be removed.  Sometimes slower 14 days even 21 days never quicker for me but others it goes after 3-5 days. Looking at the stats the weather continues to play hell with the line I had a 100 ES spike a little time ago even with interleave on unheard of for my line definitely the weather in my opinion.  I hope so anyway it better not be a fault developing.

[pxr5]

Odd. I didn't notice any storms around me recently. Also we've had storms before and nothing like this has happened. Last night my DS Max/Achieved were almost the same - approx 70550 Kbps (as they always have been). Now max DS is 78178 Kbps and achieved is 65561 Kbps. FECs seem to have jumped from the normal too. I'm wondering if something was/is going on with G.INP implementation on ECI cabs. Something happened at around 0100 this morning, and if it's happened to a few people on ECI cabs it must be something planned surely. I'm near Preston btw.

[Computerman142]

I am on an ECI cab too and I have noticed some odd goings on my line as well. Had a re connection the other night interleaving depth got reduced, then last night at 0100, interleaving depth applied at the highest and lost 5Mbps off the attainable and synced lower than normal. Hopefully there is nothing wrong with the rollout, and rather than applying G.INP, applying interleaving instead. However in regards to thunderstorms, I thought that wide area events are taken into consideration on VDSL DSLAM's, by the DLM, or does it not apply the same with ECI cabinets? Sure doesn't seem to be the case with mine, haven't had any thunderstorms in my area but I could see the errors ES racking up a lot from thunderstorms in the midlands, calmed down when they went. I'm on TalkTalk in the Selby York area if that helps.

[ktz392837]

The increased FECs are normal for interleaved.  You should also see them for download now I do as soon as interleaved is enabled.  FECs are fine they show interleaving is working.  Generally theoretically FEC is good, CRC/ES/SES is bad.  FEC/interleave should reduce CRC/ES/SES.

Yep no apparent storms, thunder, lightning either but it certainly feels there should be very muggy etc.  Don't be surprised if it does start interleave will probably be applied at an even higher inp/depth that will add even further delays getting it removed.

Nothing we can do really apart from leaving it alone.  You can try to cap your line but not worth it until the current weather passes and even then I don't like the risk of confusing the DLM.

[MTW]

Fellow ECI sufferer. The DLM is much quicker to apply interleaving than the published figures I've seen. I understood it was supposed to tolerate 720 or 1440 ES per day depending on the profile (I'm with BT), but my line regularly goes interleaved downstream with ~200 ES (and 0 SES). Once interleaved it has <5 downstream ES per day, but takes weeks or months to recover fastpath.

G.INP can't come soon enough.

[ktz392837]

It used to be 2880 ES per day! I hope OR just enable/rollout Ginp for all ECI users soon and stop this weird trial that ISPs know nothing about.

I think it still does. There's been thunderstorms here everyday since Saturday (got one passing by that is producing a lot of strikes, near constant thunder at the moment), so far DLM hasn't taken any action. Probably stick the line on interleaving now I've said that lol.

[Jaseb4920]

I’m on an eci cabinet roughly 150m away line is always rock solid 67/20 lived here just over a year and always on fast path with low ping of 8, as of early hours of Monday morning roughly 4.30 had a resync dropped to 63/20 with a ping of 20 which is very unusual, with sky and it’s always spot on to be fair! Are Openreach doing something behind the scenes hopefully going to give us 2nd rate users compared to Huawei G.INP at last as this trial looks very promising, I was on the last trial a few years ago and worked perfect for me speed gain of 7mb on download and ping went to 5 and was rock solid until Openreach pulled it

Well I was wrong. Line is now interleaved. Had 3 storms yesterday, looks as though there is more to come over the next few days.

Judging by the jump in threads mentioning the same issue i'd hedge bets that its a wide spread issue and will probably correct itself given time. Your speed is likely to increase when interleaving goes away.

Thanks 😊

I'm not convinced, at least on ECI lines.  When I got my Plusnet line Interleaved by trying to push 3dB SNRm, when I removed the SNR modification it didn't show any signs of removing Interleaving again.

With my Zen line banded, I'm not hopeful it will remove that either.  Although to be fair, its syncing at 6dB so annoyingly its within DLM specifications, I just happened to be running it rock-solid stable at 3dB before the storms.

[sof006]

Perhaps there is a long term impact caused by forcing a 3dB sync, all the more reason for FTTP to be rolled out faster. My plan is to move somewhere with Virgin broadband.

Frustratingly there's a Virgin cabinet in visible range of the BT cabinet I'm connected to, they just didn't go past the local park leaving 1/4 of the road not covered.

Though not as frustrating as FTTP being delayed here 2-3 years.
