Hello,
I am inspecting network traffic flows, and I see a large spike at a few of my site to a local IP on the ISP.
Does MSFT use a global distributed cache mechanism for Windows Updates (similar to Google Global Cache)?
Referring to my DNS log, it appears that the WSUS server preforms a lookup for ctldl.windowsupdate.com which resolves to an akamai server.
Is it correct that MSFT uses akamai for their "global distribution cache?"
Thanks,
Matt
