[AusNOG] Vocus Office 365 CDN corrupt again

[James Andrewartha]

Oddly I switched to direct DNS and got switched to Akamai WAIX, but I get 
a different MD5sum again, f4a4e53bd2869971c342a06881e445bc from

officecdn.microsoft.com.edgesuite.net is an alias for 
officecdn.microsoft.com.edgesuite.net.globalredir.akadns.net.
officecdn.microsoft.com.edgesuite.net.globalredir.akadns.net is an alias 
for a1737.dspw65.akamai.net.
a1737.dspw65.akamai.net is an alias for 
a1737.dspw65.akamai.net.0.1.cn.akamaitech.net.
a1737.dspw65.akamai.net.0.1.cn.akamaitech.net has address 23.192.239.161
a1737.dspw65.akamai.net.0.1.cn.akamaitech.net has address 23.192.239.169
a1737.dspw65.akamai.net.0.1.cn.akamaitech.net has IPv6 address 
2600:1415:b800::1737:de0b
a1737.dspw65.akamai.net.0.1.cn.akamaitech.net has IPv6 address 
2600:1415:b800::1737:de0a

Setting my DNS forwarder to 1.1.1.1 and I connect to 184.86.223.8 and now 
the install works, md5sum is b091593c99575c9f9c1f970d23cf4cc2

So that's 4 different hashes from 4 different Akamai mirrors. Well I 
tested again and 184.86.223.32 gives me b091593c99575c9f9c1f970d23cf4cc2 
too, so 4 different from 5.

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.
