Network Monitor – December 2021

Severe internet disruptions and trouble accessing Instagram continued for yet another month.

As Filterwatch reported in previous months (see reports for November 2021, and September 2021), access to Instagram continues to be disrupted in Iran. The issue is particularly noticeable at early hours after midnight, usually between 1am to 6am local time. Yet Iranian officials have not yet provided a formal explanation for the disruptions to the platform. 

According to IODA data, Iran lost a good portion of its unique ISs on 3, 10, 17, 24 and 31 December.

IODA data also showed Iran lost its BGP routing between December 11 from 6pm until 12pm the following day. Iranian users also reported disruptions on these dates, and in some areas Twitter users reported a near shutdown.

Regional Outages

According to the IODA data, only Tehran experienced disruptions on 12 December. The cause of these disruptions are not clear. 

Provider Outages

IODA data for December 2021 did not not present any information on outages at provider level.
