Major ISPs like British Telecom (core UK telephony), NTT Docomo (Japan), Vodafone Espana (showing that Vodafone isn't doing it globally), Starlink (showing it's not a old tech problem), Rogers (US ISP) are listed unsafe.
I think the 31 is a misleadingly positive picture.
Counting networks passes for journalism, and 31 is noise unless you weight each entry by size and traffic split. A pile of single-homed stubs matters far less than one big transit network, because outages and hijacks bite where traffic concentrates, and that makes the headline number feel brokn rather than reassuring.
I thought Rogers was Canadian.
