I know this is outside the NANOG area. Posting here as it might be of
interest. Ron and I welcome any comments folks on the list might have
on the report.

New Citizen Lab / ONI cross-posted blog report:
Routing Gone Wild: Documenting upstream filtering in Oman via India

Key Findings

• Data collected from Oman shows that web filtering applied by
India-based ISPs is restricting access to content for customers of an
ISP in Oman. While unusual, content filtering undertaken in one
political jurisdiction can have an effect on users in another
political jurisdiction as a result of ISP routing arrangements – a
phenomenon known as “upstream filtering.”
• Content found to be filtered includes news sites, political blogs
and file sharing sites.
• Some variability in filtering was documented, potentially linked to
certain measures to loosen filtering regulations in India.
