Does the sync drop down with the throughput?
Not that I've noticed. We're quite some way from the exchange - it's either 5 miles or 5km - can't remember, and can't remember how to find out. As I said, it usually syncs at an acceptable rate for the distance, and the throughput seems to be consistent with the sync rate. But it's a bit difficult to tell, as I'm not using any particularly fast servers on a regular basis.
I think I'm getting a better sync rate than my neighbours, but I can't be sure. Daytime throughput can be very low, evenings better and nights generally good. This is surprising, as there's not a lot of commercial or industrial premises in the neighbourhood - commuterland. But then I dont know how BT assigns lines to exchange hardware - there could be some heavy users nearby that I don't know about.
But I really don't know where these alleged line interrupts are coming from. I just don't see them.
Is the ISP a business orinented ISP? Could be they either have insufficent capacity, or traffic shape to hell during busy times (which may be daytime).
Also, if its an ISP that uses datastream or in-span handover, it could be ISP has poor capacity to exchange
Dunno. No great secret - it's Demon. They've been around for almost as long as I have. I suppose they are targetting the SOHO market these days, but I really couldn't say what sort of mix they have.
I shouldn't think they've got their own kit in our local exchange, so they're almost certainly using a BT wholesale service - don't know exactly how it works these days. They say that the problem is to do with my line to the exchange, and there's absolutely nothing I can do to prove them wrong. But it's strange that whenever they run any sort of line test, no problems show up.
My suspicion is that it's a problem with the internet kit at the exchange - wish I could remember the name of it. From the frequency at which this occurs - every 3 or 4 months - I'm suspicious about upgrade cycles, but since I don't know anyone else this is happening to, I can't prove it.
