There's a report in the blogosphere that provides an interpretation of this report
by BBC Persian that indicates the Planet (a US-based ISP) may be
revoking hosting services from an the Iranian Students News Agency
(ISNA). The report has no response from The Planet so I've sent
an e-mail (click through above link) to media contact Kristin Herring
who is listed on a press release by the ISP.
More to come (hopefully)
