As another data point, here are my graphs:

AAISP FireBrick (from f8lure): http://f8lure.mouselike.org/proxyfirebrick.asp?ID=50873

Interestingly, nothing so far this evening on the TBB graph (as a comparison, here's last Thursday)

The engineer has gone for the day, reported nothing wrong with anything. Though wasn't happy about 350m FEC errors in 3 days though, an engineer will be returning tomorrow.

Was ok last night, I wonder if TBB decided to switch the linx network used after my post

But my own line had half a million errors between 1am and 3am, some kind of issue on my line for 2 hours (looks like the same I had 3 or so weeks back). So tommorow I will very likely be interleaved and I hope DLM puts me back on fast path quickly again (it did in 2-3 days last time). Attainable rate and srn did not drop during the error burst. In fact my snr is very high at the moment as my attainable shot up again on friday but I decided not to resync the modem. So noise got injected on my line without affecting the snr. But thats a completely different issue to this thread.

My SNR has gone down to 4.4 tonight as previous days it went as low as 4.9 (Interleaved) also showing attainable rates @ 25Mbps instead of the normal 28Mbps but I think that is due to the CRC errors as I'm currently on fastpath due to the engineer. Once interleaving is applied I think I can see that moving back up a bit as I've always had 26Mbps stable on the line until BT decide to cap my line again for the 3rd time.

Let's look at my graphs this afternoon.

3 days of good results as well, dissappointed. Though it ain't the first time It's done this...

Let's look at the speeds tonight!

Had 2 re-syncs in the last 2 days but on return the IP has been the same, anyone had the same experience as well?

I know there are still IP's available as If I reset the PPPoE connection I will always be given one.

thats your line, my graphs are ok.

I did have a disconnection last night (even whilst interleaved), seemed to be cause by a short large drop in upstream attainable rate that lasted so short it resynced at same speed. But that was my line not the issue in this thread. You do have to be very careful you are diagnosing the right thing and the graph you posted is clearly something completly different.

I have reported my line issue now to BT, and also asked for a DLM reset as I am only interleaved because of 2 hours of error burst 3 nights ago. But from what I can see the packetloss issue on the graphs is gone since the routing change I posted about some days ago.

In your case I suggest you also report this to BT as a seperate incident. My gut guess is you have massive line errors causing that loss, especially if your gw graph is clean.

Yes, it has been diagnosed to be on the local loop. Had an engineer here for two days shown him the 353m errors in 3 days, though the errors are at 15, 000 per min throughout the day and don't get packet loss all the time while it even as it that.

"Openreach are going to look into changing the cable between your property and the cabinet. However as there are currently no spare pairs available, they may need to add new cable or take some from elsewhere. Though they could give a final position and advise no further engineering is possible, as the line meets the Universal Service Obligation (USO) to provide a working phone service. Unfortunately broadband performance is not covered by this USO."

Though I will suspect they will not change the cable, I don't really see how that is allowed. BT sell broadband to an "acceptable" level this isn't acceptable, also they shouldn't provide Broadband down a phone line if they aren't going to maintain/replace over Broadband faults.

There have been moments where there has been packet loss gateway and my connection so maybe there is a bit of both.
