For the last 30 years basic idea behind the Internet’ design hasn’t changed - it connects people and services with each other. However, some authorities may have a different angle on what services their citizens should be able to connect to. A regulator might require ISPs to block off selected content or IP-address space for the end-users. How is that implemented? There are many options, but the most popular one is with the help of static routes, that may be propagated locally in BGP. Mistakes in this ‘local propagation’ have happened before: most notable was the YouTube hijack back in 2008, but less famous events were continually happening all over the decade. Today we observed another one, created by Iranian ISP that affected Telegram messenger.
