Website not visible if visited from the UK

Hi,

Does any one know why my website is not visible in google when I do:
site:mywbsite

If I do it from other countries (UAE, Germany, Belgium) I can see 27 pages indexed

I launched the site this Monday, created one post and submitted it to a few social bookmarking sites (5-6).

I also pinged the site to a few ping services.

THanks
