[AusNOG] Vocus Office 365 CDN corrupt again

[James Andrewartha]

Hi Samuel,

Where did you find the logfile with the error? We're having problems 
installing Office 365 yesterday and today, the client seems to be 
downloading 
http://officecdn.microsoft.com.edgesuite.net/pr/7ffbc6bf-bc32-4f92-8982-f9dd17fd3114/Office/Data/16.0.11929.20708/stream.x64.x-none.dat
which is coming from the AARNet mirror and has an md5sum of 
82ba6ca2947f30ea7130370caf45b066

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 has address 203.13.161.144
a1737.dspw65.akamai.net has address 203.13.161.138
a1737.dspw65.akamai.net has IPv6 address 2001:388:1:180d::cb0d:a190
a1737.dspw65.akamai.net has IPv6 address 2001:388:1:180d::cb0d:a18a

The install gets stuck at 51%, even overnight. Just tested by pointing my 
DNS at 1.1.1.1 and downloading from this host:

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 has address 23.53.241.83
a1737.dspw65.akamai.net has address 23.53.241.67
a1737.dspw65.akamai.net has IPv6 address 2600:1415:b000::1735:f129
a1737.dspw65.akamai.net has IPv6 address 2600:1415:b000::1735:f11a
a1737.dspw65.akamai.net has IPv6 address 2600:1415:b000::1735:f122

gets me an md5sum of 68453f76ba26d026c6e810304a633c5c for 
stream.x64.x-none.dat

So time to contact AARNet NOC.
