Or Akamai. It turns out that I get different addresses for this FQDN  
depending whether I'm at home or at work, see traceroutes. (#include  
<stdanycastisevil.h>) At home, everything works in both Safari and  
Firefox on the Mac, at work it doesn't, even though I can open this  
URL. Also tried with the ancient Internet Explorer for Mac and with  
IE and Firefox on Windows XP, those don't seem to be bothered in the  
same way as Safari and Firefox under MacOS.

Currently, Safari tells me that certificate with SHA-1 fingerprint 9F  
B6 01 FE 68 40 BB F6 6F 55 06 28 7C 42 15 01 38 0A CA 66 is signed by  
an unknown authority. I can't copy/paste the details and they don't  
show any areas that seem problematic to my untrained eye.
