5/24/22, 7:45 PM Myanmar: Data on internet blocks and internet outages following military coup | OONI This is evident through IODA data, which shows that all signals consistently drop between 01:00 to 09:00 local time every night from 15th February 2021 onwards.

This synchronization is in stark contrast to the first Internet outage that occurred during the coup on 1st February 2021; in the time since, it appears that ISPs have developed and honed techniques to enforce and relax Internet connectivity shutdowns according to pre-planned schedules. https://ooni.org/post/2021-myanmar-internet-blocks-and-outages/ 14/16
