Another observation is I was online at the last error burst, I ran speedtests and packet loss tests, all showed no indication of problems.  Which was at odds at the rate the ES was rising.

Pages were failing to load for me, and I had a message saying I'd dropped the ftp connection to my server.  I tried to do a speedtest, but TBB wouldn't load.  I had 3 tabs with the spinning wheel just going round in circles.  The odd thing is that I did a tracert to the BBC which was perfectly fine.

You two have have had a terrible time with Broadband your sync rate is 70+ Mbps I would be more concerned when your getting 13-18 retrains per day and then become banded you have nothing to worry or complain about.

Ummmm... It's service impacting and renders my connection unusable.   Thats how each time it happened I noticed something odd was going on because the connection was a pile of p00. 
Not much good having a sync speed of 70+Mbps when you cant do anything with it because its dropping packets all over the place.  ???

The first thing I noticed was a message saying that my ftp session to the server had been dropped.   I then tried to open a web-page which failed to load.  I couldn't load this site, the BBC or TBB.   I couldnt even get to do a speedtest because no pages would load.

See graph below from HG612 stats - note average of 22916 Err Secs per day.  See also MDWS showing 35k CRCs per min - that equates to 10's of millions of CRCs per day.   
I think DLM would certainly have something to day about that - or would have done if I hadnt been here at the time to do a manual resync and put a halt to it.   

Same with Chrys - twice this week he also was around to see it happen and put a stop to it or else DLM would sure as hell taken action.  The average bod in the street wouldnt know what to do or have DSLstats running to notice that and end up getting severely penalised. If this is more widespread, then there will be people start to wonder why their speeds have been reduced /banded for no apparent reason.     

In my book that is something wrong.

Thank you banger, I think I ran across that script earlier when searching.   There was also a openWRT one that I found.   I need to double check the router commands in the script, but it should do the trick nicely :)

In my case it stopped by itself, I didnt want to lose my 74mbit sync and since everything was functioning I left it alone.  However if the ES count got close to the threshold then I would have intervened.  It seems your ES count is a lot higher than mine reached which probably explains why yours was service impacting.  Bear in mind it could be totally unrelated why I got my bursts, I just mentioned it as I had still remembered it when you made your post.

>>> I didnt want to lose my 74mbit sync and since everything was functioning I left it alone

Unfortunately as mine continued to rise, I had no alternative. I didn't want to as it meant that I went from 78,841 down to 72,884 but if I hadn't then DLM would have got me resulting in interleaving and a further drop to 68Mbps.

Some odd happened this morning.
At 04:33 there was a short outage at the DSLAM which lasted for 6 mins.
At 04:39 I came back up with a sync speed of 79987.  This is max sync speed and the highest Ive sync'd in many months.  It's not real though as my crosstalker is now up again.

Today for the first time I can remember in well over a year, I dont have that regular 10-11am spike.   However, it looks like it may have shifted to 6-7am.  Too early to tell. 
The outage at the cab indicates possibly something going on.  5 min outage at that time of night is about right for a f/w update or config changes.

I had a resync at 02:45am this morning for no reason bar a drop in power from 5.7 to 3.5 on up and down and reduction in US snr. now wondering if this was a config change on the eci cab. Will check cab firmware just in case its changed. I seem to have gathered DS snr overhead at around 6.6 which is unusual for my line based on past issues. If the cab config is different I will let you know. I had previously capped the modem so there is gain to be had now but I am tempted to leave the cap in place until perhaps we see the return of g.inp..

I am afraid to say it's happened again Kitz you probably have already noticed it to, something goes mad with your HEC error's would like to help but it's way beyond me.

Thanks NS.    It appeared to do its usual thing whereby the daily spike triggered off a large amount of errors. 

I wasn't around at the time it occurred, but when I got back I noticed that web pages were extremely sluggish. 
A quick look at DSLstats showed that the CRCs were running at 20,000 per min and the Err/Secs at about 3,000 per hour.

I did a couple of quick speedtests (attached below).  I was at the time syncing at a full 79987/20000 and you can see how erratic it makes the throughput.
If you look at the pale green line at times throughput is zero, peaking to 11 Mbps for a single thread.   Latency was pretty grim too :(

So I powered down the modem and it came back up at 73Mbps where its been sat ever since.

Now there is one thing that is REALLY odd.   I fully expected DLM to kick in the next morning like it does on previous occasions and apply INP.
But it didn't.   Why it didn't I have no idea.   
The only possible reason I can assume is that sufficient other people are seeing the same thing OR because we'd had really bad thunderstorms that day, it was attributed as a Wide Area Event.

I doubled checked no T/Storms in your vicinity at that time of day and DLM must have seen a local wide area event at your DSLAM the cause unknown, It's looks promising but lets see only time will tell

We had massive storms here on the 19th.  Granted they may not have been at 11 am when my errors started, but we did in the afternoon.   

It was really weird, I'd got home saw the errors, rebooted the modem, let the cats out and was feeding the fish.   Bluish hazy skies but could feel the static building up in the air. I'd thrown a few tetra sticks in the pond, and as usual Zigs came over and I poured some sticks in my hand as he loves sniffing them.   From out of the blue there was a simultaneous flash bang that made me jump so much the tetra sticks went flying and I spilt them all over the patio.   Both cats were petrified and ran for cover.  Whatever it hit could not have been more than 1/2 mile away.
By 4pm it had escalated to black skies and torrential rain that flooded several areas making some major roads almost impassible.

your spikes must be really annoying, reporting the fault will be near impossible as if it doesnt happen whilst the engineer is there then they wont recognise it.
