Limelight.
I have a 10MB pcap file.
It's not hard to crush a 3mb connection though, so I'm not sure how
important this case is going to be. I wish msoft's updater would look
at average throughput over the first 5 minutes of an update, then limit
itself to half of that. If they did that, I would never even know the
updates were running. Or just limit non-critical updates to 128kbps.
It might take 10 weeks to finish, but would I really care? Or for
Pete's sake just let me configure a limit of my choosing.
Anyway, I do appreciate you taking the effort to look for answers at the
CDN level. Just seems to me that Microsoft could easily make the
problem not exist.

Oh, that's unlikely to be of significant help, but I can check. What is
the CDN it's connected to?

Windows update is using my entire 3mbps connection right at this
moment.
I have a pcap, but it's from my side and in this case i don't have
access to the provider side.

It's Patch Tuesday, so I figured I'd pop in to remind people that have
issues with Microsoft Updates to get packet captures of the problems
at least one level upstream of whatever device is doing the rate
limiting. When you have them, let me know so we can coordinate with
whichever CDN and Microsoft to look into why it is happening.
We're specifically looking for times when there are dozens of TCP
connections open for the transfer or when the CDN is ignoring TCP
norms and sending more bits than the customer is limited to.
