[AusNOG] Vocus Office 365 CDN corrupt again

[James Andrewartha]

Hi Phil,

Akamai is now giving us Vocus Akamai servers, and they are giving us a bad 
file too - 139.218.20.187 has an md5sum of 
4f93c7595d3965dc836e6b0eb7b06c05 for stream.x64.x-none.dat

Thanks,

If anyone from Vocus is on this list, or someone here has any contacts at Vocus, it'd be much appreciated if you could raise it with someone who can look into it.
