thanks for the "quotes", Mark. I agree. https://www.caida.org/publications/presentations/2018/investigating_causes_congestion_african_afrinic/investigating_causes_congestion_african_afrinic.pdf page 23: Results Overview • No evidence of widespread congestion - 2.2% of discovered link showed evidence of congestion at the end of our measurements campaign page 34: Conclusions • Measured IXPs were congestion-free, which promotes peering in the region https://conferences.sigcomm.org/imc/2017/papers/imc17-final182.pdf my conclusion: s/congestion/congestion or the lack thereof/g Frank Habicht PS: yes, i could name peers that once had inadequate links into an IXP. but for how long did that happen? (yes..., any minute is too long...)
