I'm troubleshooting an issue we seem to be having between our CDN and TW Telecom (our office's ISP). If someone else on TW Telecom in the RTP area could run a few download tests from a browser and wget/mtr on linux, that would be great. We're seeing intermittent packet loss and subsequently slow downloads on one hop of the path - 108.161.186.2. Our backup connection with AT&T seems fine. Even those not on TW Telecom can help, I guess.What I'm looking for:1) Which datacenter you're hitting, from here: http://108.161.188.2242) Average download speed from a browser for this ~70MB User Guide.http://extrcdn.extremenetworks.com/wp-content/uploads/2014/04/ExtremeXOS-15.5-User-Guide.pdf3) Average speed from this:

^Perfect! Thanks.Interesting that you're seeing loss on alter.net, but glad (in a way) to see loss on the 108.161.186.2 address.
