This is a good thing. Using system fonts means less bandwidth consumed, more privacy (presumably), faster rendering, and better consistency with the rest of the user's environment.
The only failure could be not serving a web font as a failsafe, but I'm not going to count that against them because I hate the idea of web fonts.
Edit: Actually, nevermind all that. Microsoft is serving Segoe UI as a web font in addition to referring to the system copy.[1] If that's not rendering properly, either Microsoft got the URL wrong or something is fubar on the browsers concerned.
