NHS ‘snap off’ online access to RTE News?

A GP from Derry writes:

All primary care workers in NI have NHS e-mail addresses and can access the web from work via a central Health &Social Services spine. It has just decided that the RTE news website contains “inappropriate material” and blocked access. It was allowed up until today, now when you try to access it you get the blocked, inappropriate material message. BBC, Google, The Guardian, MSN news and Al Jazeera all allowed, just RTE singled out.

Seems harsh. Is it political?
