Dead giveaway is that streaming movies keep breaking up via iplayer.
Anyone else ?

I haven't tested ping times, but everything looks perfectly quick and
the iPlayer here is streaming fine.

Normally I get around 42ms, but today it's a tad over 150ms.
I'm barely getting over 1.5Mb/s too, whereas normally I'm at 4Mb/s.
Alan.
Looking at my graph of ping times on flure, it shows them increasing
from the normal 40 or so to reach about 140 between about 12:30pm and
4:30pm, since when it's fallen back to 40 again. I had thought this
feature of a "plateau" during the working day (or in this case the
working afternoon) was now a thing of the past. My guess is that it's
returned because Internet usage is currently exceptionally high, with
workers trying to get tasks finished before they go on holiday for
Christmas.

Yes, it's "pants" here too today (Buckingham) So much so, I've given
up using 'net based sources for my timekeeping needs. I now have a
local GPS driven NTP server here, working fine. uS precision, instead
of 100's of mS variation during the day.
Cheers.

Sensible ntp software works network delays into the equation.

which is all I seem able to expect from Demon nowadays.
Looks like congestion/shaping to me?

Well, if it is, it wasn't happening to me yesterday:

Generaly yes, but......
Even NTPD has trouble with the service I get, resulting in slow drifts
of several hundred ms back and forth throughout the day, if I use 'net
servers as it's reference tickers.
The problem is worse, as the latency variation is always asymetric and
random. :-(
I have a local GPS referenced server now however. uS accuracy and
stable as a result. :-)

Ignition or Injector driver QRM, direct into the phone line (nearby,
overhead?) kicking the router as a result.
Any PLT/PLA devices in use (power line networking) ?

Purely as a matter of curiosity, what application do you have that requires
microsecond-level timing accuracy?
Regards,
Chris
Hi Chris..
I have uS accuracy now, but I needed only mS accuracy, but more
importantly, a "Reliable" with "no drift" timing service, that Demon
seem unable to provide these days..
The app involved is "Faros" (Google for it, it's from "DxAtlas") That
controls a HF receiver and monitors a worldwide chain of beacons,
recording their reception strength, and timing, so as to determine if
the signal came the long or short way round.
If you go to "http://www.ncdxf.org/beacons.html" that will hopefully
explain all. The Faros program is also linked from there, under "Tools
for Listners" then under Windows etc...
You'll find my monitor status linked as "G0WBX" from the monitor
stations page.
Cheers.

Fascinating! Thanks - it's always interesting to learn what other people get
up to.
