I'm getting these ping results for microsoft.com and outlook.com:

Arthurs-iMac-2:~ arthur$ ping microsoft.com

However, when I ping google.com I get these results:

It's not just for me either:

The service status is fine:

outlook.com service status from https://status.live.com/detail/outlook

Is there a particular reason why this is happening?

Perhaps they setup a firewall and are blocking ICMP. Why are you trying to PING Microsoft.com. –  Zoredache May 14 '13 at 18:45
    
Microsoft doesn't offer a ping responding service. Is there some reason they should? –  David Schwartz May 14 '13 at 19:13

Hosts can decide not to respond to ICMP requests (like pings). Doesn't mean they're slow or down, they're just not responding to them.

Outlook.com (157.56.242.235) doesn't answer pings.

65.55.58.201 is not the usual Microsoft.com, it resolves to 00001001.ch, which appears to be part of the German/Switzerland MSDN site. It also doesn't answer pings.

Hmm, that IP resolves to Microsoft.com for me –  Doorknob May 14 '13 at 18:47
    
Yeah, that's weird. www.00001001.ch seems to lead to the swiss MSDN. :) Perhaps part of a CDN(?)... –  Ƭᴇcʜιᴇ007 May 14 '13 at 18:52
