If you weren't checking the counts, would you have noticed anything?

[William Grimsley]

Yeah, I noticed audio problems with Skype.

[Weaver]

Skype is of course just the kind of application that you could very well expect to be sensitive to dropped packets.

Exactly. Dropped packets = underlying fault.

I don't think 4 SES is grounds for reporting a fault and getting an engineer out, they could have been caused by almost anything, like a bit of electrical arcing as something is switched on but before the switch is fully closed.

Ooo, that sounds interesting. What's "electrical arcing"? Is this someone trying to bend the line?

[roseway]

It means sparks. It's more likely to happen when you switch something off - as the connection breaks, the electricity tries to keep on flowing, and arcs over the tiny gap. The slower the switch contacts move apart, the longer the period of arcing is. Arcing causes high levels of wide band radio interference.

Or transatlantic wireless transmission as Mr Marconi called it. 

[roseway]

He did indeed

[William Grimsley]

Ah, so it could be something switching off in the house that's starting to fail for example?

Like a lamp switch for example had this issue last year every time it was switched on in the living room at dusk with spikes of ES showing in dslstats at the same time.

then listened to the contact switch on the lamp when going into the on position which generated audible electric crackles/arching. replaced the switch and no more errored seconds from lamp 

[krypton]

I noticed the same with the switch from the exhaust hood in the kitchen. It could generate several hundreds or thousands of crc errors. Now with g.inp they are all corrected on the fly.

Ouch!

Why, oh why, oh why has my line just got in a mess again! There were no Downstream ES on the line! The only thing that has improved is my IP profile!

I've got two options. I either just live with my banded line (as that is what DLM wants to do) or I get an engineer visit.
