This is an anecdotal answer but, because of what I state in my last paragraph, I believe my answer holds for more than just one occasion.
I have been living in Addis Ababa since February, and I was affected by the week-long internet shutdown in May.
During that period, I was able to pay for internet at the Hilton and Intercontinental hotels in the city centre. The speed was decent at both hotels (for being Ethiopia, that is1), with the internet at Hilton a tad more reliable. Both of these are owned and operated (at least partially) by the Ethiopian government, which is likely to be the reason why they were able to circumvent the shutdown and had internet access.
1. You seem to be well-informed, but be aware that even when things are good, internet is usually quite slow in Ethiopia.
