Evidence snapshot for Saint Helena, Ascension and Tristan da Cunha
The CONTEXT practices address Saint Helena and Ascension Island specifically, but not Tristan da Cunha as a territory in its own right.
Saint Helena's broadband infrastructure transitioned from satellite-only connectivity to Google's Equiano subsea cable in October 2023, cutting latency to London from 657 milliseconds to 131 milliseconds, though uptake remains limited with only ~10% of purchased capacity in use due to ageing copper last-mile networks and high retail pricing (~£120/month). Ascension Island underwent a three-phase feral cat eradication programme (2002–2006) funded at approximately £650,000, which enabled seabird recolonization—Ascension frigatebird nesting attempts grew from 2 pairs in 2012 to 1,493 in 2020–21. The practices contain no substantive evidence about Tristan da Cunha as a distinct jurisdiction.
