Blocked.org.uk/Testing policy

Objectives

Objective	How met
1 Test most popular websites	Use CommonCrawl data as reference Work with Common Crawl and / or others to get reference data
2 Find filter blocks	Wide pass for filters Use extra capacity for single tests for retesting
3 Locate court order blocks	Start by testing sites from public sources or blocked by court order in different jurisdictions Widen by testing sites blocked by filters Use Lumen to locate potentially blocked domains Use other public data including court information for testing
4 Locate domain seizures	Single pass using spare capacity against all datasets
5 Keep data up to date	Prioritise sensitive data, eg likely mistakes and court orders Retest filter blocks periodically
6 Create as much data as possible	Use full capacity of probes; keep as busy as their line capacity allows Do less testing in parallel Stop the slow lines from restricting the throughput of tests
