I travel to singapore every quarter and in
my experience the bandwidth sucks. You get nowhere near advertised speeds on wireless networks and the international connectivity is highly contended on the wired links. My links in the UK are much faster for comparable cost.
Lived in Singapore for a while in 2008, was never impressed with .sg internet. I hated having to register my mobile so their government could find out what I'm looking at etc. Also, they have a less intrusive version of the "Great Firewall of China".
Singapore is a very small island. Easy to build advanced infrastructure, and their government advocates improving technology.
