Social Networking Uptime
My favorite blog in the world has a post about the year to date downtime of various social networks which is revealing. Not a single one achieves the famous “three nines” uptime SLA (although Amazon’s S3 service offers a two nines 99.99% uptime guarantee).
Yahoo 360 isn’t a real social network, but it had great uptime
The best of these is Yahoo 360, with 99.9938% uptime over the last two months, followed by Myspace (99.969%), Facebook (99.8822%), Linked In (99.7024%), and finally Windows Live (99.4482%). MySpace was only down for 25m, while MSN Live Spaces had an embarrassing 7hrs 25m of downtime.

There appears to be some confusion here with the meaning of “three nines”.
Three nines means 99.9% uptime. So, Yahoo and Myspace achieved three nines.
Your link to a blog discussing Amazon's S3 service suggests that they have a THREE nines (99.9%) guarantee, refunding even more if they don't even achieve TWO nines (99%). Your mention of 99.99% doesn't seem to be part of the guarantee.
