Akamai's recent "State of the Internet" report ranks the UK as #25 globally (and #16 in Europe) in average broadband connection speeds. Ireland is ranked 13, globally
This, however, does not discourage Netflix from establishing its first non-Americas operation in the UK and Ireland "in early 2012".
"Upon launch, Netflix members from the UK and Ireland will be able to instantly watch a wide array of TV shows and movies right on their TVs via a range of consumer electronics devices capable of streaming from Netflix, as well as on PCs, Macs and mobile tablets and phones. Further details about the service, including pricing, content and supported devices, will be announced closer to launch".
Netflix expanded to Canada (see "Netflix to the Rescue" - here) and Latin America (here), earlier this year. See also - "Netflix: Video Streaming Performance" - here.
