At least seven major disruptions were observed this April in Iran. The weekly Friday internet shutdowns in Sistan and Baluchistan province have been ongoing throughout April in a similar pattern to <\/span>March<\/span><\/a> and <\/span>February<\/span><\/a>. These shutdowns continue as protests often take place around the same time as Friday prayers, especially in the city of Zahedan. <\/span><\/p>\n

Similar to Sistan and Baluchistan province, we have also observed a pattern of internet shutdowns in Alborz province; on 14 April for about one hour, then on 20, 24, and 27 April, further disruptions were observed in the province.\u00a0<\/span><\/p>\n

According to <\/span>Kentik<\/span><\/a> data provided to Filterwatch, a new kind of disruption in April, which we have not seen in a while, was the result of <\/span>hijacking IP space<\/span><\/a> by AS41689 of AsiaTech on 10 April. According to an anonymous source, this is part of Iran\u2019s national <\/span>SD-WAN <\/span><\/a>program. However, Filterwatch cannot independently verify this claim and currently how this will impact internet users in Iran is unknown.\u00a0<\/span><\/p>\n

\u201cNothing on the Internet that behaves like this except BGP-based DDoS mitigation like Prolexic. Is this part of some Iranian DDoS defense? If so, they screwed up the ROAs and AS41689's announcements are getting filtered because most are RPKI-invalid, limiting its efficacy\u201d said Doug Madory, Director of Internet Analysis at Kentikinc commented in a <\/span>Twitter post<\/span><\/a> about this incident on 14 April.\u00a0<\/span><\/p>\n

According to IODA data on <\/span>8 April<\/span><\/a>, there was a major dip in internet traffic at 11:30 am UTC (3 pm local time), which affected Zanjan and Hamedan provinces.\u00a0<\/span><\/p>\n

On 3 April there was a major internet disruption in the city of Qom according to the IODA <\/span>data<\/span><\/a>.\u00a0<\/span>This could\u00a0 potentially be in response to a <\/span>call<\/span><\/a> to protest during between 3-7 of April though it is difficult to verify.\u00a0<\/span><\/p>\n

Manipulating connections after calls to protest and or on the days of protests, is one of the <\/span>main methods<\/span><\/a> used by the authorities to control and silence protests, especially during the past few months.<\/span><\/p>\n

In <\/span>Alborz<\/span><\/a> province, which is close to the capital city of Tehran, IODA <\/span>data<\/span><\/a> showed a brief disruption on 14 April, which lasted around 1.5 hours. During April, Alborz province experienced around 10 hours of disruptions without any prior warning or explanation from the authorities.\u00a0<\/span><\/p>\n

On 29 April, Alborz province experienced a near total internet shutdown from 10:30 am local time (7 am UTC time), which coincided with a \"call to remove compulsory hijab\" on the same day.\u00a0<\/span><\/p>\n

On 14 April, Arvan Cloud\u2019s Radar <\/span>showed<\/span><\/a> disruptions on data centres. On the same day, Alborz and Zanjan province\u00a0<\/span>faced<\/span><\/a> internet disruptions. This was the 4th week of disruptions in Alborz province, and Zanjan province faced a 10 hour disruption in early morning. This may have been in reaction to the a <\/span>call to protest<\/span><\/a> on 15\u00a0 April.<\/span><\/p>\n
