Tonga’s likely lengthy Internet outage

2022 only has 19 days of existence but so far this January, there have already been four significant Internet disruptions:

2. An Internet shutdown in Kazakhstan because of unrest.
3. A mobile Internet shutdown in Burkina Faso because of a coup plot.
4. An Internet outage in Tonga because of a volcanic eruption.

It started with the large eruption of Hunga Tonga–Hunga Haʻapai, an uninhabited volcanic island of the Tongan archipelago on Friday, January 14, 2022. The next day, Cloudflare Radar shows that the Internet outage started at around 03:00 UTC (16:00 local time) — Saturday, January 15, 2022 — and is ongoing for more than four days. Tonga’s 105,000 residents are almost entirely unreachable, according to the BBC.

When we focus on the number of requests by ASN, the country’s main ISPs Digicel and Kalianet started to lose traffic after 03:00 UTC and by 05:30 UTC January 15, 2022, Cloudflare saw close to no traffic at all from them, as shown in the graph below.
