Internet?" where answers range from "Extremely Often" to "Never or almost Never." Freedom House's Freedom on the Net report also uses expert analysis to assess whether internet shutdowns have occurred, but instead of surveying multiple experts, Freedom House identifies and partners with a single expert to conduct an analysis. Freedom House asks the question "Does the government intentionally disrupt the internet or cellphone networks in response to political or social events, whether temporary or long term, localized or nationwide?" Generally expert analyses are more prone to false positives and fewer false negatives (i.e. identifying shutdowns that other sources cannot confirm), than remote sensing methods with manual oversight.

Initiative has volunteers install software on their computers to check websites from access points around the world, then confirms those results with manual observations. These methods are prone to more false negatives and fewer false positives (i.e. all shutdowns that these sources identify can be confirmed by other sources) than expert analyses.

A comparatively new method for detecting internet shutdowns is remote sensing with automated oversight. These methods have been praised as more ethical and efficient as they do not endanger in-country volunteers. However these methods have yet to produce regular datasets.
