Plug your landline number into:

That'll give you lots of info about your line and exchange. The rates
it quotes are generally pretty accurate.
I can hear a hum on 17070 which I am sure degrades my ADSL connection.
There's a bit of hum on our ADSL2+ I don't think it has any effect at
all. 50 Hz is way out of the band used by ADSL, the uplink carriers
don't start until 26.075 kHz and the downlink ones go up to 2.2 MHz.
What does knock back the acheivable ADSL speed are strong LW and MW
broadcast stations, which varies between day and night of course.
If the hum is really loud it *may* have and effect but then just
report a POTS vault and get it fixed.
A hum may not of itself be a problem but it is usually indicative of a
ground loop, which can be.

It is not the truth of Marxism that explains the willingness of
intellectuals to believe it, but the power that it confers on
intellectuals, in their attempts to control the world. And since...it is
futile to reason someone out of a thing that he was not reasoned into,
we can conclude that Marxism owes its remarkable power to survive every
criticism to the fact that it is not a truth-directed but a
power-directed system of thought.
