Using this as a data source:

and selecting Google Mail and Postini Services at the items to measure, he arrives at this:
| Date | Service | Duration | Reason |
|---|---|---|---|
| 4/9/2010 | Postini | 2:24 | Unspecified Emergency Maintenance |
| 4/7/2010 | Core Gmail | 11:20 | HTML mode email down for "a small number of users" |
| 4/2/2010 | Postini | 2:08 | Failed Postini update |
| 3/16/2010 | Core Gmail | 9:51 | Inbound/Outbound Email was not routing |
| 3/15/2010 | Core Gmail | 4:38 | Users unable to access gmail accounts |
| 3/10/2010 | Core Gmail | 0:50 | Users unable to access gmail accounts |
| 3/8/2010 | Postini | 0:29 | Anti-Spam not anti-spamming |
| 3/4/2010 | Postini | 0:58 | Anti-Spam not anti-spamming |
| 2/25/2010 | Postini | 7:46 | Users unable to send email |
| 40:24 |
Total runtime (2 services) 2304
48 days, 24 hrs day, 2 services
Effective uptime
98.24%
I have not done my own math here to verify, just thought it would be interesting to share. Note that he gives them twice as many runtime hours since he's counting two services. I would tend to halve that, resulting in double the downtime percentage.
I thank Google for publishing their outage information, by the way.
Just a data point for the next time someone is asking you for more nines than is reasonable.

I feel the lack of Information Security Training is the main cause for most of the attacks to occur. A well trained security professional will know how to defend the networks, hack the own network ethically and uncover the hidden vulnerabilities. I came across one such training in Ethical Hacking by EC-Council. I came to know about it by seeing the posting of the latest Certified Ethical Hacker (CEH) courseware launch by EC-Council mentioned in CCURE.
EC-Council has released the much awaited Version 7 of its Certified Ethical Hacker.
Check here https://eccouncil.org/cehv7.aspx
They are offering FREE CEHv7 Seats for the Launch Class
Read :CEH V7 is coming, move away QEH, CPTS, CREST, and others" Check the posting (http://www.cccure.org/)
