Hi,
Hosting365.ie have a datacenter on Baggot Street in Dublin, Ireland.
What I need is the full street address, and building name etc. I do
not know much more about it other then that they also use this
location for providing wireles access in the CBD of Dublin.

I cant answer your question. But I've been playing with Goole Earth,
trying to find the new building:

Hosting 365 Ltd. 
Unit 5 
Beckett Way
Park West Business Park
Nangor Road
Dublin 12
Ireland 

and came to this coordinates: 53º19'52N 6º22'30W. I cant see a thing
in Goole Earth, the area is not detailed ):

But I dont think this is the place you are looking for.
