I am surprised that they using server names like "alpha.telemetry.microsft.com". when I see something like "microsft" in an E-mail or link I immediately suspect that somebody is trying to fake being from Microsoft. Or are these spelling errors in the article? Edit: these domain names are in the report too. Very strange. I would get very nervous if I saw "microsft" in a firewall log.
its right there with spynet2.microsoft.com and spynetalt.microsoft.com ;). Plus you have to remember W10 spy^^telemetry switches to hardcoded IPs if DNS fails.
