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. ----- Mike Hammett Intelligent Computing Solutions Midwest Internet Exchange The Brothers WISP
