Expert analysis is used by several organizations to identify internet shutdowns. The Digital Society Project (DSP) sends out surveys to experts around the world and aggregates the results into a single score.

Some organizations, like Freedom House, use expert analysis to assess whether internet shutdowns have occurred. They identify and partner with a single expert to conduct an analysis.

Expert analyses are more prone to false positives and fewer false negatives than remote sensing methods with manual oversight. This means they're more likely to incorrectly identify shutdowns, but less likely to miss actual shutdowns.

Access Now uses technological methods to detect shutdowns, but then confirms those shutdowns using news reports, reports from local activists, official government statements, and statements from ISPs. This approach helps to ensure accuracy.

The OpenNet Initiative has volunteers install software on their computers to check websites from access points around the world, then confirms those results with manual observations. This method is prone to more false negatives and fewer false positives than expert analyses.

Remote sensing with automated oversight is a relatively new method for detecting internet shutdowns. It's been praised for being more efficient and ethical, as it doesn't put in-country volunteers at risk.

Natural disasters can cause internet outages by damaging infrastructure. This can happen in various ways, such as through direct destruction or indirect damage to the local electricity grid.

Floods, hurricanes, and earthquakes are just a few examples of natural disasters that can cause internet outages. In 2018, Cyclone Fani caused significant damage to internet infrastructure.

Inclement weather, like heavy snow, thunderstorms, and heavy rain, can also cause outages by damaging infrastructure or making it difficult for maintenance crews to access and repair the network.

Weather or natural disasters can have a devastating impact on our internet connectivity. Extreme weather events like Hurricane Florence 2018 and Cyclone Fani 2018 directly destroyed local ICT infrastructure.

Floods, hurricanes, earthquakes, and other natural disasters can damage internet infrastructure, causing outages. The Monash IP Observatory and KASPR Datahaus have tracked the impact of these disasters.

Inclement weather like heavy snow and thunderstorms can cause outages by damaging the infrastructure or making it difficult for maintenance crews to access and repair the network. Heavy rain can also cause similar issues.

Natural disasters like hurricanes and earthquakes can cause widespread outages by damaging multiple parts of the internet infrastructure.

Solar storms can be a major threat to our global Internet infrastructure, causing months-long outages.

Researchers have identified potential mitigation measures, such as user-powered mesh networks, to help minimize the impact of these storms.

These mesh networks allow users to connect directly with each other, bypassing traditional infrastructure.

The current Internet infrastructure is not robust enough to withstand the intense radiation and charged particles emitted by solar superstorms.

Solar storms are a reminder of the importance of having a backup plan in place for our critical systems.

Scheduled maintenance or unexpected repairs on the internet infrastructure can cause outages, as seen when Verizon customers suffered service outages due to a "software issue" impacting wireless service.

Thousands of Verizon customers nationwide reported service outages after the network experienced a “software issue” impacting wireless service for some users. This highlights the importance of maintaining a stable internet infrastructure.

Equipment failure, such as servers, routers, and switches, can also cause internet outages, as reported when Verizon Fios internet outages impacted millions of customers on the East Coast.

The widespread internet outage that affected major websites like PlayStation Network, Amazon, and UPS was caused by a brief issue with the global content delivery networks Amazon Web Services and Akamai.
