rate-limit or not rate-limit

I discovered some nice thing this afternoon…
In my company, we are multi-homed since a few months. Our second provider provides us a 2Mbits pipe over a FastEthernet link in a colo… theorically! πŸ™‚
Today, I got alarms due to a very high traffic coming from this ISP… Peaks up to 20Mbits! I sniffed some ports and identified the source , emailed him to ask why he generated so much traffic. Answer came back soon: “download of Linux ISO files”, Mhhhhh…
This traffic should have been rate-limited on the ISP router… Damned!?
I tested some FTP sessions to remote sites (into the ISP AS and outside):

ncftp …om/linux/9/en/iso/i386 > get shrike-i386-disc1.iso
shrike-i386-disc1.iso: 638.12 MB 5.25 MB/s
ncftp …om/linux/9/en/iso/i386 > bye

Please, dear loved ISP, don’t change anything, loose your “enable” password! πŸ™‚
PS: Of course, no name given here πŸ˜‰
