Ping is not very informative or accurate. =20
If you run a traceroute, which is also not very accurate,=20
you can get some idea about where the delay appears to be.
Is it the DSL segment? Is it somewhere else that traceroute can show =
you?
The nice thing about delays that are this long is that=20
9000 ms is long enough it won't just be lost in the noise...
It wouldn't be surprising if it's in your DSL,
and if your DSL has changed to a lower speed=20
(which looks like it might have happened),
then maybe something _is_ wrong with your DSL,
or maybe the slower speed is causing traffic backups that weren't a =
problem
when you were getting 512 kbps, or you're getting TCP retransmissions,
but maybe the problem is somewhere else in the network.
