I recently had a very traumatizing experience with a client I was consulting for and whose preferred mode of connection is Safaricom 4G. For two days I was struggling to figure out why what seemed so obvious (in my mind) was NOT working with Safaricom while I had tested the same with JTL and Access Kenya links. It turned out that Safaricom truly tamper with traffic to the Internet. This includes even VPN traffic. This test result presented here is not a surprise to me at all. Safaricom's DPI (Deep Packet Inspection) systems are so robust and advanced that they can do ANYTHING with your traffic. I wrote a private email to Stephen Chege of Safaricom (we all remember him) but didn't receive even an acknowledgement. The problem I had - with DNS and VPN still stand unresolved. And this is why I am always suspicious about the dalliance (for lack of a better word. I am thinking in Dholuo and translating to English) between Safaricom and the govt, especially since one of them was given a senior govt job!

Hello listers.
CIPIT has been conducting network measurements on Kenyan Internet Service Providers (ISPs) since June 2016 using assorted techniques. Between 6 – 10 February 2017, the data indicated the presence of a middle-box on the cellular network of one provider, Safaricom Limited (AS33771) that had not previously presented any signs of traffic manipulation. Middle-boxes assume dual-use character in that they can be used for legitimate functions (e.g., network optimisation) and can simultaneously be used for traffic manipulation, surveillance and aiding censorship.
In light of such dual uses, this report makes clear that service providers operating middle-boxes must communicate to the public in a transparent manner the justification for such activity. This is especially relevant as government bodies announce plans to monitor and possibly censor the Internet during Kenya’s current electoral processes.
