Thanks for the data, very interesting. It appears right that I called this measurement around a 
"balck hole" which we can now see clearly.

Also interesting to note is that more than 90% of the Uganda-IX traffic is dependent on 
international connectivity or was the local network around the IXP also shutdown?. I am 
wondering also if that may also be based on CDNs and their related external management 
and cache fill issues. 

Regards,

Paulos
