Additionally, I discuss the DFZ, de-peering and partitions before delving into a sample breakdown of traffic volume for a typical mid-sized US provider by connectivity type: transit vs peering vs embedded cache vs IXP. Interesting stuff!

Internet service returning to #Afghanistan following Taliban-directed internet shutdown to "prevent immorality" beginning at 11:50 UTC.

The shutdown, a first for the country, lasted almost two full days.

Yesterday, the internet in Afghanistan went dark.

The Taliban ordered the country's first-ever nationwide shutdown, a devastating blow to its growing digital economy and a profound assault on human rights.

Les Taliban bloquent Internet pour 1 journée complète et envisagent de revenir à la 2G pour "éviter l'immoralité". Ça me rappelle une histoire, bien française elle, de "3 Go par mois", et de l'obsession de blocage du porno.

Internet down for a second day in Afghanistan as country's first-ever internet blackout continues.

Directive from Taliban govt is to revert to 2G-only service as a way to "prevent immorality."

The ongoing internet shutdown in Afghanistan is the outcome of what many feared when the Taliban took over in August 2021.

As of August 2024, we hadn't seen much change with respect to internet service in the country, as I detailed in this blog post:

The internet shutdown in Afghanistan is an extension of ban on fiber optic services that was implemented in more remote parts of the country earlier this month.

Blackout in Afghanistan as Taliban orders internet service downed at 12:38 UTC (5:08pm local).

Earlier this month, Taliban banned fiber optic internet in a rural province to “prevent immorality.” This shutdown follows brief national outage minutes earlier from 11:33 to 11:53 UTC.

Multiple reports of a brief #Starlink outage earlier this morning corroborated by a significant drop in HTTP requests between 04:00-05:00 UTC.

Large burst of #BGP announcements seen at that time as well. Announced IP address space also saw some shifts.

Beginning at 04:27 UTC today (Sep-15), Starlink suffered a brief but global service outage. This is most widespread service outage since Jul-24 when Starlink was down for more than two hours.

Nearly all AS14593's BGP routes were briefly withdrawn at the time of the incident.
