FOCI’21, August 27, 2021, Virtual Event, USA Padmanabhan et al. Figure 6: IODA’s BGP signals show the differences in timing and extent of the Internet connectivity outage that occurred on Feb. 1 (the day of the coup). While some ASes observed an initial drop in connectivity at 21:00 UTC on Jan 31, others experienced an outage just after midnight UTC on Feb 1. These timing differences are also visible when examining the outages’ end-times. Further, a few ASes experienced only minor outages during this period. Figure 7: Nightly Internet outages and cellular restrictions. From February 14 to April 28, complete Internet connectivity outages occurred every night in Myanmar. In this figure, we use data from IODA and Kentik to show a two week period where these nightly outages occurred. In the "Kentik Traffic" curve—which shows the traffic seen by Kentik for all ASes in Myanmar aggregated together—we observe a significant reduction after March 15; this reduction corresponds with the beginning of cellular data restrictions that have been in place from March 15 onward. In Figure 3, we break down the traffic by individual ASes and show that cellular ASes, in particular, observed a massive reduction in traffic from March 15. 36
